Why Did the Radio Lock and Ask for a Code?
The Becker radio in the Crossfire activates its security whenever the power supply is interrupted. It's shared technology with the Mercedes SLK — a typical European radio anti-theft approach.
Most frequent cause: battery replacement or a flat battery. Disconnecting the Crossfire battery triggers the SAFE mode on reconnection.
Other causes:
- Buying the Crossfire used without the Becker code card
- A blown fuse in the radio circuit
- Electrical work that involved disconnecting the battery
The Becker code is specific to the unit's 8-digit serial, not the vehicle. Any mechanic or dealer can look up the code without the serial.
Can't Find Your Radio S/N? Follow The Steps Below for Chrysler Crossfire 2005
The first step is finding the radio serial.
Most drivers assume the code depends on the Chrysler model or year, but in reality, the unlock process depends on the unique radio unit's serial number.
Each radio has its own serial tied to the security system.
This is even better, because if you have bought an aftermarket radio, the VIN or other vehicle-specific data wouldn't help.
Based on the radio used, you can retrieve the serial directly from the display or by looking at the label on the radio chassis.
2005 Chrysler Crossfire Factory Head Units
For 2005 the Crossfire continued with the same Mercedes/Becker-supplied radio family it launched with in 2004. There is no Mopar MyGIG, no Uconnect, and no three-letter sales code panel on the bezel - identification is by the Becker model number printed on the chassis label and by what is visible on the radio face. The 2005 model year added the SRT-6 high-performance variant, which used the same head unit choices.
Becker BE 6806 (Base). Single-DIN AM/FM/CD with a slot-load CD on the right, a monochrome dot-matrix display, rotary volume/tune knobs and six numbered preset buttons. The face shows "Becker" branding and no Infinity badge. This is the unit fitted to entry-trim Crossfires. The model designator BE 6806 is printed on the chassis label and the unit cross-references to Mercedes-style part numbers (Type ZH 29).
Becker BE 6806 Infinity. Mechanically the same single-DIN BE 6806 chassis but specified with the factory Infinity external amplifier on premium trims and the SRT-6. The bezel typically carries an "Infinity" mark and the speakers are amplifier-driven. The chassis label still reads BE 6806.
Becker BE 6802. Variant with a DTM control on the lower row of bezel keys (in place of the C/C button on the base unit). Same single-DIN form factor, same dot-matrix display, same six presets. Less common than the BE 6806 across the 2005 lineup.
Quick identification: if the bezel has no Infinity mark and shows a C/C button on the lower row, you have the BE 6806 base; if the same layout has an Infinity badge, it is BE 6806 Infinity; if the lower row carries a DTM button, the unit is BE 6802. Sales-code identification methods that work on Mopar/Uconnect radios are not applicable here - read the printed Becker model number on the chassis label after removing the unit.
View Your Serial Number via the Radio Screen
These are the steps you need to follow for 2005 Chrysler Crossfire:
The 2005 Chrysler Crossfire uses a Becker radio system (shared with its Mercedes-Benz SLK platform). Common Becker model numbers include BE6802, BE6806, BE6808, and BE6812. These Becker units do not support any on-screen method for viewing the serial number.
The only way to locate the serial number is to pull out the radio from the dashboard and read the label on the back of the unit. The label shows both the model number (4 digits after "BE") and the serial number (8-digit code below the model number).
Check the S/N by Pulling Out the Radio Unit
If the serial does not appear on display, the next step is checking the radio itself.
Many Chrysler radios require physical access to the ID label attached to the unit.
Usual approach:
- Start by completely powering down the engine - pull the key out.
- Then lift the trim panel.
- Next, unscrew the mounting points and slide the radio forward.
- Look for a factory sticker showing the serial number.
The Becker radio in the 2005 Crossfire sits in the center of the compact dashboard. To extract it:
- Apply a prying tool to gently pry off the surrounding bezels around the radio.
- Remove the fasteners located in each corner of the radio mounting bracket (typically 4 screws).
- Apply gentle pressure and ease the radio forward from the dashboard.
- Locate the serial number label on the back side of the Becker unit.
Tip: Some Crossfire owners may need Becker-specific release keys instead of screws. Look for small slots on both sides of the radio face – if present, slide release keys in to free the unit.
Pull the 2005 Crossfire Radio to Read the Serial
The 2005 Crossfire shares its head unit family with the 2004 cars and uses Becker (Mercedes-platform) units that do not expose the serial via any on-screen menu. To read the serial reliably, the radio has to come out of the dash using DIN release keys - the same style of extraction used on Mercedes SLK/R170 and other Becker-equipped vehicles.
Safety Notice
Switch the ignition fully off and remove the key. Disconnect the negative battery terminal and wait several minutes so the SRS capacitors discharge. Do not pull, splice, or probe yellow-jacketed wiring or yellow connectors behind the dash - those belong to the airbag circuits. Have your code-retrieval information ready before you reconnect the battery, because the radio will prompt for its security code as soon as it powers back up.
Tools You Will Need
You need a set of four DIN release keys - the slim U-shaped wire keys that engage the slots at the corners of the radio face. A soft cloth or microfibre to rest the unit on once it is out, and a phone camera to photograph the chassis label, are also useful. A plastic pry tool may help if any decorative trim ring around the bezel needs easing first. No 7 mm socket or four-bolt cage hardware applies on the Crossfire; this is a Mercedes-style installation.
Removal Overview
Insert a DIN key into each of the four slim slots at the corners of the radio face until you feel a click - this releases the internal spring catches. Keep gentle outward pressure on the keys while you draw the radio straight out of the dash; do not twist or rock the unit. Pull it forward only as far as the rear harness allows, then release the antenna lead and disconnect the multi-pin connector(s) on the rear. After the radio is out, press the small tab on the side of the chassis next to each key to free the DIN keys.
Where the Serial Is Printed
The serial number lives on a printed label on the metal chassis - typically on the top or rear face of the unit, alongside or directly under a barcode. The label also shows the Becker model number (for example BE 6806) and a Mercedes-style part number. The serial is the alphanumeric string clearly separated from the part number and is often labelled S/N or Serial. Photograph the entire label so the model, part number, and serial are all captured.
Reinstallation Tips
Reconnect each plug until it clicks home and route the wiring so nothing is pinched. Slide the radio back into the DIN cage until all four spring catches re-engage with an audible click. Reconnect the battery, switch the ignition on, and the radio should display its CODE prompt, ready for entry of the unlock code retrieved against the serial you just recorded.

How Serial Numbers Usually Look on These Crossfire Radios
The 2005 Chrysler Crossfire uses a Becker radio produced by Harman (for Mercedes-Benz). The serial number format is distinct from standard Uconnect radios:
- Model number: Starts with
BEfollowed by 4 digits (e.g.,BE6802,BE6806) - Serial number: An 8-digit numeric code printed below the model number on the rear label
You must provide both the model number and serial number to obtain the correct unlock code. The Crossfire Becker radio is a separate system from the Uconnect platform used in other Chrysler vehicles.
Typical Serial Number Formats Used on 2005 Crossfire Radios
Serial numbers on the 2005 Crossfire's Becker head units follow Mercedes/Becker conventions rather than the FCA Mopar conventions used on contemporary US Chrysler/Dodge/Jeep models. On the chassis label you will typically see two distinct fields that matter for code retrieval: the Becker model number (for example BE 6806) and the serial number itself, which is printed as a separate alphanumeric string and is often prefixed with S/N or Serial. Because the exact serial format can vary between production batches and supplier runs, the dependable rule is to copy what is on your label exactly as printed.
Becker BE 6806 (Base / Infinity)
The model identifier shown on the bezel and chassis label is BE 6806 - this is the same on every unit and is not the serial. The serial is the separate alphanumeric string on the same label, typically located next to a barcode. Reported serials on Becker units in this family commonly include a short letter prefix followed by digits; whatever appears under or beside the barcode and is labelled S/N is the value you need.
Becker BE 6802
The chassis label shows BE 6802 as the model designator. As with the BE 6806, the serial is the separate alphanumeric string on the label and is distinct from the Mercedes-style part number, which on Becker labels often begins with A followed by long digit groups (for example a string resembling A 193 820 xx xx).
Reading Tips
Do not confuse the model number (BE xxxx) with the serial - the model is the radio family identifier and is the same for every unit of that type, while the serial is unique to your radio. Anything starting with A followed by long digit groups is normally the Mercedes/Daimler part number, not the serial. Watch for the digit 0 versus the letter O, and the digit 1 versus the letter I - they look similar on these labels but generate different unlock codes. Capture every character, including any leading zeros, because a single wrong character will yield a wrong code.
How Serial-Based Chrysler Crossfire Radio Unlock Works
Vehicle radios use anti-theft codes tied to the radio unit itself rather than the model or production year.
- The generator identifies your Chrysler radio via serial-based verification.
- After entering the serial into the form above, the system identifies the radio family and generates the code that you need.
- Use the code to unlock the radio immediately.
- The online process is quicker and more accessible than visiting the Chrysler dealer.
How to Enter the Radio Code
Now that you've found the radio serial and received the unlock code, the next step is entering it into your radio.
Chrysler original head units display a locked screen when ready for input.
The process is straightforward, but button layouts and confirmation methods may differ slightly depending on the radio version installed in your Crossfire.
In-depth Entering Instructions for Crossfire 2005
To enter the unlock code on the 2005 Chrysler Crossfire's Becker radio:
- Turn the ignition to ON and turn on the radio. The screen will show "CODE" or "SAFE".
- Press preset button 1 repeatedly until the first digit of your code appears on screen.
- Do the same with button 2 for the second digit, button 3 for the third, and button 4 for the fourth.
- Hold the Enter or OK button for a few seconds to submit the code.
Note: Becker radios will lock after a few incorrect attempts, displaying "SAFE". Leave the radio turned on for about 60 minutes to clear the lockout before trying again.
Correct Entering Process
Once you have the unlock code for your 2005 Crossfire radio, the entry follows the Mercedes/Becker pattern rather than the FCA Mopar preset-button method used on contemporary US Chrysler MyGIG and Uconnect units. The numeric preset buttons on the radio face are used to dial in each digit, and a confirmation control validates the entry. Be deliberate; attempts are limited.
Limited Attempt Warning
Becker radios in this family typically allow up to three code attempts before the display shows WAIT. When that happens, the radio must remain switched on for approximately ten minutes before CODE reappears and another attempt is permitted. Repeated wrong entries can extend the lock-out, and after several cycles the unit may impose a 24-hour wait period before any further attempt is allowed. Do not guess - verify each digit on the screen against your code sheet before you confirm.
Step-by-Step Code Input
Turn the ignition to the accessory or run position so the radio powers up and shows the CODE prompt. Each numeric preset (1 through 5) corresponds to one digit position of the code; press a given preset the number of times equal to that digit, or - on some firmware revisions - press and hold the preset until the desired digit is displayed. Work through the digits in order, watching the display update after each press, until all digits are visible on screen. When the displayed sequence matches your code sheet exactly, confirm the entry by pressing and holding a confirmation control - commonly the right-most preset (button 6) or a dedicated OK/SRC control - for several seconds, depending on the unit's firmware.
If the Code Is Rejected
If the radio rejects the entry, do not immediately retry. Leave the ignition on so any WAIT timer can run down fully, and re-check every character of both the serial and the issued code against your records. Re-enter only once the timer clears and you are certain the digits are correct. If the radio remains locked after a verified re-entry, contact your code provider rather than continuing to guess; further wrong attempts will only deepen the lock-out.
Fixing Common Code Entry Problems for 2005 Crossfire
After several incorrect code attempts, the Becker radio displays "SAFE" — the anti-theft lockout. Different from touchscreen Uconnect, this looks like "SAFE" on the small display.
To clear: Leave the radio powered on (ignition ON or ACC) for approximately 60 minutes. Avoid turning it off during this period. After the timer expires, "SAFE" disappears and code input returns.
The Becker serial number format is completely different from Uconnect radios. It's an 8-digit code printed on the back of the unit, directly below the model number (BE6802, BE6806, etc.).
If the sticker is worn or damaged, check a small card in the glove box — some Crossfire owners kept the original code documentation. Otherwise, the radio must be decoded via the serial.
The Becker unit's rear label shows two separate numbers: the model number (e.g., BE6802) and the serial number (8-digit code printed directly below the model number). You need both — the model tells you the variant and the serial generates the unlock code.
If it didn't work, double-check that you submitted both correctly. Note that the Becker serial is only 8 digits, not 14 like Uconnect units.
If the Becker isn't displaying a code, the anti-theft hasn't activated. The lock fires only after a power disconnect.
To force a code prompt: disconnect the car battery briefly, then restore power and start the car. The radio will show "CODE" after boot.
The Crossfire Becker uses physical preset buttons for code input — no touchscreen is involved. Press button 1 repeatedly to cycle to the first digit, button 2 for the second, button 3 for the third, button 4 for the fourth. Then press and hold Enter or OK for 2-5 seconds to confirm.
If you cycle past the right number, keep pressing the same button — it cycles back to 0 so you can reach the correct number.
