What Caused the Radio to Lock?
The Becker radio in the Crossfire triggers anti-theft whenever the power supply is interrupted. This is the same Becker system used in Mercedes-Benz vehicles of the same era — a factory European radio anti-theft approach.
Most frequent cause: battery replacement or a dead 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
- Workshop repair that required disconnecting the battery
The Becker code is tied to the unit's 8-digit serial, not the vehicle. No one can look up the code without the serial.
Radio Serial Number Explained - Finding It on Your Chrysler
The starting step is finding the radio serial number.
Many people assume the code depends on the Chrysler model or year, but actually, the unlock process depends on the unique radio unit's serial number.
This number identifies the exact head unit installed in your Chrysler Crossfire.
This is even better, because if you have an aftermarket radio, the VIN or other Chrysler-specific data wouldn't help.
Based on the radio version used, you can see the serial directly from the display or by looking at the label on the radio chassis.
Factory Radios on the 2006 Chrysler Crossfire
For 2006 the Crossfire kept its Mercedes/Becker head unit family. The Roadster body had been added the previous model year, but the audio choices remained the Becker single-DIN units rather than any Mopar MyGIG or Uconnect head. Identification is via the Becker model number on the chassis label and via what is visible on the radio face - there is no three-letter sales code panel like the one used on contemporary US Chrysler/Dodge/Jeep MyGIG units.
- Becker BE 6806 (Base). Single-DIN AM/FM/CD with slot-load CD on the right, monochrome dot-matrix display, rotary volume/tune knobs and six numbered presets across the lower face. "Becker" branding on the bezel, no Infinity badge. The chassis label is printed
BE 6806and the unit is the Mercedes/Becker Type ZH 29. - Becker BE 6806 Infinity. Same single-DIN BE 6806 chassis specified with the factory Infinity external amplifier on premium trims and the SRT-6. Bezel typically shows an "Infinity" mark; speakers are amp-driven rather than radio-driven. Chassis label still reads
BE 6806. - Becker BE 6802. Variant with a
DTMcontrol on the lower row of bezel keys (in place of theC/Cbutton on the base unit). Same single-DIN form factor, same dot-matrix display, same six presets. Less common than the BE 6806 across 2006 production.
Quick identification: bezel without Infinity mark and with a C/C button on the lower row is BE 6806 base; same layout with an Infinity badge is BE 6806 Infinity; lower row showing a DTM button means BE 6802. To confirm, draw the unit out of the dash with DIN release keys and read the model designator printed on the chassis label.
Using Hidden Radio Menus to Find the Serial
These are the steps you should follow for 2006 Chrysler Crossfire:
The 2006 Chrysler Crossfire features a Becker radio system (shared with the 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.
Your only option to find the serial number is to extract the radio from the dashboard and find the label on the back panel of the unit. The label shows both the model number (4 digits after "BE") and the serial number (8-digit code underneath the model number).
Releasing the Radio Unit to Access the S/N on the Tag
If the serial number cannot be accessed on-screen, use the removal method.
Most Chrysler Crossfire OEM radios include a tag with the serial number printed on the chassis.
The process:
- Remove key from ignition.
- Lift away surrounding dashboard trim.
- Loosen screws holding the radio.
- Move slightly to inspect the label.
The Becker radio in the 2006 Crossfire sits in the center of the compact dashboard. To extract it:
- Apply a prying tool to carefully remove the trim panels around the radio.
- Remove the bolts located in each corner of the radio cage (usually 4 screws).
- Apply gentle pressure and ease the radio free from the dashboard.
- Locate the serial number label on the back side of the Becker unit.
Tip: Some Crossfire owners may need DIN extraction keys instead of screws. Look for small holes on both sides of the radio faceplate – if present, use extraction tools to release the unit.
Access the S/N by Taking Out the 2006 Crossfire Radio
- Generation context. The 2006 Crossfire is mid-cycle in the 2004-2008 production run and continues with the Becker (Mercedes-platform) single-DIN head units used since launch.
- Where the serial lives. The Becker units carry their serial number on a printed label on the metal chassis - not on the screen. Pulling the unit is required to read the serial cleanly.
Safety Notice
- Switch the ignition fully off and remove the key before doing anything in the centre stack.
- Disconnect the negative battery terminal and wait several minutes so the SRS capacitors discharge.
- Avoid all yellow-jacketed wiring and yellow connectors behind the dash - they carry SRS/airbag signals and must not be probed or pinched.
- Have your code-retrieval information ready before you reconnect the battery, because the radio will display
CODEas soon as it powers up again.
Tools You Will Need
- A set of four DIN release keys (the slim U-shaped wire keys that engage the slots at each corner of the radio face).
- A soft cloth or microfibre to lay the radio on once it is free.
- A phone camera to photograph the chassis label after removal.
- Optional: a plastic pry tool if any decorative trim ring around the bezel needs easing first.
Removal Sequence
- Insert one DIN key into each of the four slim slots at the corners of the radio face; push until you feel a click as the internal spring catches release.
- Keep gentle outward pressure on the keys and draw the radio straight out of the dash - do not twist or rock the unit.
- Pull the radio forward only as far as the rear harness allows, then release the antenna lead and disconnect the multi-pin connector(s) on the rear panel.
- To free the DIN keys after the radio is out, press the small tab on the side of the chassis next to each key.
Locating the Serial Label
- Look at the top, side, and rear of the chassis until you find a printed white label with a barcode.
- The serial is the alphanumeric string near or directly under the barcode and is often labelled
S/NorSerial. - Distinguish it from the model designator (
BE xxxx) and from the Mercedes-style part number (often beginning withA) - those are separate fields. - Photograph the entire label so all three fields are captured for reference.
Refitting
- Reconnect each connector firmly until you hear or feel the latch.
- Slide the radio back into the DIN cage until all four spring catches re-engage with audible clicks.
- Reconnect the battery, switch the ignition on, and confirm the radio is showing its
CODEprompt before entering the unlock code retrieved against the recorded serial.

Typical Serial Number Examples for 2006 Crossfire
The 2006 Chrysler Crossfire uses a Becker radio made by Harman (for Mercedes-Benz). The serial number format is different from standard Uconnect systems:
- Model number: Starts with
BEfollowed by 4 digits (e.g.,BE6802,BE6806) - Serial number: An 8-digit numeric code located below the model number on the back sticker
Both are required both the model number and serial number to generate the correct unlock code. The Crossfire Becker radio is a completely different system from the Uconnect platform used in other Chrysler vehicles.
Common S/N Formats on 2006 Crossfire Radios
Serial numbers on the 2006 Crossfire's Becker head units follow Mercedes/Becker labelling conventions and are printed on the chassis label rather than embedded in any on-screen menu. On a typical label you will see at least three fields of interest for code work: the Becker model number (for example BE 6806), a Mercedes-style part number, and the serial itself. Because exact serial formats can vary between production runs, the safest practice is to copy what is on your label exactly as printed.
Becker BE 6806 (Base / Infinity)
- The chassis label prints the model designator as
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 next to a barcode and often prefixed with
S/NorSerial. - Treat any string that is clearly separated from the model designator and the part number, and is sitting under or beside the barcode, as the serial.
Becker BE 6802
- The chassis label shows
BE 6802as 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
Afollowed by long digit groups (for example a string resemblingA 193 820 xx xx).
Reading Tips
- Do not confuse the model number (
BE xxxx) with the serial - the model identifies the radio family, while the serial is unique to your unit. - Anything starting with
Afollowed by long digit groups is normally the Mercedes/Daimler part number, not the serial. - Watch for the digit
0versus the letterOand the digit1versus the letterI- the print can make them look similar but they produce different unlock codes. - Capture every character including any leading zeros; a single wrong character will yield a wrong code.
Code Entry Process for 2006 Crossfire
When you obtain the correct unlock code based on the S/N, you can restore normal functionality by entering it into the unit.
The code entry process depends on the head unit design, but most 2006 Crossfire systems follow a similar structure using preset buttons, touch controls, or rotary knobs - depending on if it's a factory or an aftermarket unit.
You will typically see ENTER CODE displayed on screen.
Step-by-Step - The Correct Way to Enter It
To input the unlock code on the 2006 Chrysler Crossfire's Becker radio:
- Turn the ignition to ON and power on the radio. The display 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 confirm the code.
Note: Becker radios may lock after a few incorrect attempts, displaying "SAFE". Keep the radio turned on for approximately one hour to reset the lockout and try again after.
Step-by-Step Code Input Guide
The 2006 Crossfire Becker radios use the Mercedes/Becker code-entry 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 dial in each digit and a confirmation control validates the entry. Be deliberate, because attempts are limited.
Limited Attempt Warning
- Becker units in this family typically allow up to three code attempts before the display shows
WAIT. - When
WAITappears, the radio must remain switched on for approximately ten minutes beforeCODEreappears and a further attempt becomes possible. - 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.
Code Entry Procedure
- Turn the ignition to the accessory or run position so the radio powers up and shows the
CODEprompt. - Use preset 1 for the first digit of the code: press the button the number of times equal to that digit, or - on some firmware revisions - press and hold it until the desired digit appears on the display.
- Use preset 2 for the second digit, preset 3 for the third, preset 4 for the fourth, and preset 5 for the fifth, watching the display update after each press.
- Once all digits are visible on the screen and match 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/SRCcontrol - for several seconds. - If the entry is accepted the radio will resume normal operation; if it is rejected the unit will indicate an error and may show
WAIT.
Behaviour on Incorrect Entry
- If the radio rejects the entry, do not immediately retry - leave the ignition on so any
WAITtimer can fully expire. - Re-check every character of both the serial and the issued code against your records before re-entering.
- If the radio remains locked after the wait period and a verified re-entry, contact your code provider rather than continuing to guess; further wrong attempts will only deepen the lock-out.
How to Unlock a Chrysler Crossfire Radio After Power Loss
Car radios use anti-theft codes dependent on the radio unit itself instead of the model or production year.
- Our lookup service works by matching your Chrysler Crossfire radio's serial number.
- Once the serial number is submitted, the system identifies the radio family and retrieves the corresponding code.
- Use the code to unlock the radio immediately.
- The online process is quicker and more accessible than visiting the Chrysler dealer.
Understanding Unlock Issues with Your Crossfire
After several incorrect code attempts, the Becker radio displays "SAFE" — the anti-theft lockout. Different from touchscreen Uconnect, this appears as "SAFE" on the small display.
To clear: Keep the radio powered on (ignition ON or ACC) for approximately 60 minutes. Do not switching off the ignition during this period. After the timer expires, "SAFE" disappears and the prompt returns.
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). Both are required — the model tells you the variant and the serial generates the unlock code.
If the code was rejected, verify that you submitted both correctly. The serial is short the Becker serial is only 8 digits, not 14 like Uconnect units.
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 hold Enter or OK for 2-5 seconds to confirm.
If you accidentally go past a digit, keep pressing the same button — it cycles back to 0 so you can reach the correct number.
If the Becker isn't displaying a code, the anti-theft hasn't activated. It activates only after the radio losing power.
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 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 label is unreadable, check a code card in the glove box — some Crossfire owners have the original code documentation. If no card exists, the radio must be decoded via the serial.
