What Caused the Radio to Lock?
The Ram 1500's Uconnect RA3 locks automatically whenever the battery is removed or replaced. These trucks encounter this regularly because:
- Battery replacement — the single most common trigger. Just disconnecting the battery triggers the lock.
- A blown fuse — common after electrical accessory or audio installation.
- Buying the truck used without the code.
- Truck stored until battery fully discharges.
The code is derived from the radio's serial number — not the VIN.
Locked 1500 Radio? Here's Exactly How to Get the Code
Getting your radio code takes only 4 easy steps.
- Locate your radio's serial - this is the only information required to generate the correct unlock code.
Unlike dealership lookup, no VIN is needed. - When you've found the S/N, type it into the form above.
Our system checks it against a database of supported units and automatically retrieves the matching radio code. - In most cases, the code appears instantly on the screen after payment and is also sent to your email , just in case.
If we need to check it manually, you'll be notified before checkout. - Once you get it, simply enter it into the radio to restore the functionality.
Entering the Radio Security Code
After locating the S/N and retrieved the unlock code, the final step is entering it into your radio.
Ram OEM units display a CODE prompt when ready for input.
The process is straightforward, but button layouts and confirmation methods may vary depending on the radio version installed in your 1500.
In-depth Input Instructions for 1500 2017
To input the unlock code on the 2017 Ram 1500's Uconnect 8.4":
- The screen displays "ENTER CODE" or ---- after a battery event.
- Use the on-screen touchscreen keypad to enter each digit of the 4-digit code.
- The radio restores instantly after the 4th digit – no confirm button needed.
Lockout: 3 wrong attempts = 60-minute lockout. Leave ignition ON. Turning it off restarts the timer.
Correct Entering Process
Once the unlock code has been retrieved, the 2017 Ram 1500 radio is unlocked directly from the head unit - no scan tool or dealer visit is needed.
- Limited attempts: Mopar/Uconnect units only accept three incorrect tries before going into a WAIT state, so confirm every digit before entering anything.
- Place the ignition in RUN/ACC so the radio powers up but the engine stays off.
- Wait for the display to show
CODE,Enter Anti-Theft Code, or a similar prompt. - On the 8.4 Uconnect units (RA3/RA4) and the 5-inch RA2, tap the on-screen number pad to enter each digit; on the RA1, use the numbered preset buttons to key in the code in sequence.
- Confirm the entry with the on-screen OK/Enter button or the tune/menu knob, depending on the radio variant.
- If
WAITappears after three wrong attempts, leave the radio powered with the ignition in RUN for a continuous 30 minutes (the truck may be driven during this time) before trying the correct code again.
How to Find the Serial Number on Your 2017 Ram 1500 Radio?
The useful thing to know is that factory radios use a specific S/N to identify each unitindividually.
Your security system matches the code directly to the serial.
Unlike vehicle-specific data like VIN or registration information, it is not determined by the model or production year, so you'll be able to generate it even if you have a radio that you installed afterwards.
Depending on the manufacturer and radio installed in your Ram 1500, the retrieval method is different.
Here are the most reliable ways to locate it.
Which Head Unit Is in Your 2017 Ram 1500?
2017 was the final model year that the Ram 1500 stayed entirely on the Harman-built Uconnect platform; the Panasonic 4C transition happened for the 2018 model year. Identification still comes down to screen size and the NAV tile on the home menu.
- Uconnect 3.0 (sales code RA1) - base radio on the Tradesman; small non-touch display flanked by hard buttons and rotary knobs, no Bluetooth, AUX/USB media inputs only.
- Uconnect 5.0 (sales code RA2) - typical on SLT/Big Horn; a 5-inch colour touchscreen flanked by hard buttons with rotary tune/volume knobs, adds Bluetooth hands-free.
- Uconnect 8.4 (sales code RA3) - mid-tier 8.4-inch touchscreen with no surrounding hard buttons and no NAV tile on the home menu.
- Uconnect 8.4N (sales code RA4) - top-tier head unit on Laramie/Limited; identical 8.4-inch bezel to the RA3 but with a NAV tile on the home menu and an HD Radio logo on FM playback.
Display-Based Serial Number Retrieval
These are the steps you need to follow for 2017 Ram 1500:
The 2017 Ram 1500 4th-generation is equipped with the Uconnect 8.4" (RA3) touchscreen. Whether your 1500 is a work truck or a Laramie Longhorn, the serial number is accessible without tools via Dealer Mode:
Climate Button Method:
- Turn the ignition to ACC or ON.
- Hold the Climate Up, Climate Down, and Front Defrost buttons simultaneously for about 5 seconds.
- Dealer Mode appears on the 8.4" display.
- Go to: System Info → Radio Part Info → Serial Number.
Alternative Method: Hold Temperature Up (red) and Temperature Down (blue) together for 5 seconds to open Engineering Mode, then navigate as above.
Using Hidden Radio Menus to Find the Serial
On 2017 Ram 1500 trucks equipped with the 8.4-inch Uconnect screen, the head unit's built-in dealer/diagnostic menu prints the radio serial number on the touchscreen, so the unit does not have to be removed from the dash. The smaller RA1 (Uconnect 3.0) and RA2 (Uconnect 5.0) head units do not have a publicly documented on-screen serial routine.
Uconnect 8.4 (RA3) and Uconnect 8.4N (RA4)
- Set the ignition to RUN/ACC and let the Uconnect interface finish loading.
- Simultaneously press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST buttons.
- Keep the three buttons pressed for around 7-10 seconds until the dealer/diagnostic screen appears.
- Open the radio or system information section to view the serial number listed on screen.
- Photograph the screen so the characters can be transcribed accurately later.
Releasing the Radio Unit to View the S/N on the Tag
If the serial does not appear on screen, the next step is checking the radio itself.
Many Ram radios require physical access to the ID label attached to the unit.
Usual approach:
- Start by completely turning off the engine - pull the key out.
- Then lift the dashboard bezel.
- Next, unscrew the mounting points and pull the radio forward.
- Look for a barcode label showing the serial number.
If Dealer Mode is unavailable on your 2017 Ram 1500, the RA3 radio must be physically removed to access the serial label:
- Remove the center stack bezel – The Ram 1500's bezel covers the 8.4" display and climate controls. Insert a plastic pry tool around the edges to release the friction-clipped panel.
- Remove the 4 Torx T20 screws – Holding the radio to the dash bracket.
- Slide the radio forward – Ease the unit out far enough to read the serial label on the side surface.
1500 Note: Higher trim models can include thicker trim pieces. Apply steady pressure when prying. Wiring can remain connected.
Serial Number on the Unit
When the screen-based method is not an option - for example on the RA1 or RA2 head units - the chassis label on the back/top of the radio is the next reliable source for the serial number on the 2017 Ram 1500.
- Safety first: switch the ignition off, remove the key, disconnect the negative battery terminal, and wait a few minutes; never tug on the yellow airbag/SRS connectors and stick to plastic trim tools to avoid shorts and broken clips.
- Tools you will need: plastic trim removal tool set, 7 mm socket, T20 Torx bit, Phillips screwdriver, flashlight.
- Lift the rubber beauty plate stamped with the RAM logo at the top of the dash bezel to expose two hidden T20 Torx screws and remove them.
- Lift the rubber mat in the small cubby above/beside the radio to expose another hidden T20 Torx screw and remove it.
- If the truck has a centre console, remove the rubber mat in the front console cubby; the centre dash bezel then pulls rearward over the gear lever.
- Pull the centre dash bezel rearward; the remaining clip retainers release with firm hand pressure.
- Disconnect the hazard switch and any HVAC/control connectors at the rear of the bezel, then set the trim aside on a clean cloth.
- Remove the four 7 mm screws (two upper, two lower) holding the radio cage to the dash support bracket.
- Pull the radio straight rearward and unplug the antenna lead and the multi-pin power/data connectors on the back.
- Locate the printed sticker/barcode label on the top or side of the radio chassis - this carries the serial number along with the part number.
- Photograph the label and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

These are the Common Serial Formats
The 2017 Ram 1500 Uconnect 8.4" (RA3) comes from Harman or Continental. Standard serial number prefixes:
T00AM– Harman VP2 Uconnect 8.4" (primary format)T00BE– Continental Uconnect 8.4" versionTM9– Earlier Harman production
Radio designations: RA3 (standard 8.4"), VP2 (8.4" with Alpine audio). Example: T00AM394958584 (14 characters).
Reminder Do not mistake the part number (P05064... or 68...) with the serial number. Only the serial is needed for code generation.
S/N Patterns and Prefixes
The factory radios fitted to the 2017 Ram 1500 use the standard Mopar/Continental/Harman head-unit serial style. The exact prefix depends on which Uconnect tier was installed and which supplier built the unit.
Uconnect 8.4 (RA3) and Uconnect 8.4N (RA4)
- Typically printed as a 14-character alphanumeric string on the chassis label.
- Commonly begins with
T- frequent prefixes areT00AM,TM9, orTQ1- or withA2Con Continental-built variants. - Often a continuous run of letters and digits with no dashes or spaces on the printed sticker.
Uconnect 5.0 (RA2) and Uconnect 3.0 (RA1)
- Usually carries a Mopar/Harman-style serial on a chassis label; treat the printed sticker on the unit as the authoritative reference.
- Always copy the serial exactly as printed and avoid guessing missing characters.
Fixing Common Code Entry Problems for 2017 1500
No "ENTER CODE" prompt means the anti-theft hasn't activated yet. It only locks after a power interruption.
Force the lock: disconnect the battery briefly, then reconnect and turn ignition to ON. The prompt appears on startup.
Code failure on the Ram 1500's Uconnect 8.4" almost always means a serial number mismatch. The RA3 label shows both the serial number (14 chars, starts with T00AM, T00BE, or TM9) and the part number (P... or 68...) — only the serial generates the code.
Double-check your serial, paying attention to 0 vs. O and 1 vs. I. Reach out for a free re-check if needed.
The Ram 1500 Uconnect 8.4" RA3 uses touchscreen-only code entry. Press each digit directly on the digital keypad. No physical buttons are needed. The radio unlocks without a confirm step after the last digit.
The Ram 1500's Uconnect RA3 locks after 3 wrong entries. The screen keeps showing "ENTER CODE" but ignores all taps during the lockout.
To reset: Keep ignition ON for 60 full minutes without cutting power. Any power interruption resets the 60-minute wait. Work-use 1500s that get turned off frequently must complete the full wait in one session.
The label on the Ram 1500's RA3 radio shows the serial number (14 chars: T00AM, T00BE, or TM9 prefix) and the part number (P05... or 68...). Only the 14-char serial generates the code.
Confirm you're reading the label on the radio unit itself, not a dealer label added later.
