Entering the Radio Security Code
After receiving 2016 Dodge Challenger unlock code from the serial number, you're ready to reactivate the radio.
Some drivers hesitate at this stage because input process can look different across radio versions, but it's usually quick.
When the radio shows dashed lines, it means the unit is waiting for the correct numbers.
Entering Process Explained
To unlock the Challenger's radio Uconnect 8.4":
- With ignition ON, the screen shows "ENTER CODE" or ----.
- Tap the on-screen touchscreen keypad to enter your 4-digit code. The Challenger's large 8.4" screen makes each tap easy.
- The radio auto-unlocks after the 4th digit — no OK button.
Lockout Warning: 3 wrong entries trigger a 60-minute lockout. Leave ignition ON for the entire hour. Turning the Challenger off adds to the wait.
Detailed Input Instructions for Challenger 2016
Once the unlock code has been retrieved for a 2016 Challenger radio, it can be entered directly at the head unit - no scan tool or dealer visit required.
- Limited attempts: Mopar/Uconnect head units only accept a small number of wrong tries (commonly three) before going into a WAIT/LOCK state, so confirm every digit before pressing it.
- Place the ignition in RUN/ACC so the radio powers up while the engine stays off.
- Wait for the display to show
CODE,Enter Anti-Theft Code, or a similar prompt. - On Uconnect 8.4 (RA3/RA4) units, type each digit using the on-screen number pad; on the Uconnect 5.0 (RA2), key in the digits on the smaller touchscreen number pad.
- Confirm the entry with the on-screen OK/Enter button.
- If
WAITappears after incorrect attempts, leave the radio powered with the ignition in RUN for the documented cool-down period (around 30 minutes of continuous run-state) before trying the correct code again.
How Serial Numbers Work and Where to Find Them on 2016 Dodge Challenger Radios
The important fact to know is that factory radios use a unique serial number to identify each unit.
Your security system matches the code directly to this serial.
Different from car-specific data like VIN or registration information, it is not determined by the model or production year, so you'll be able to get it even if you have an aftermarket radio.
Depending on the maker and radio installed in your Dodge Challenger, the retrieval method is different.
These are the best ways to locate it.
Identify Your 2016 Challenger's Factory Radio
The 2016 Challenger continues the same Harman-built Uconnect 3C lineup as 2015. The same three sales codes are offered and a quick look at the screen size and the NAV behaviour tells you exactly which one you have.
RA2 - Uconnect 5.0: standard on SXT and base R/T builds. 5-inch touchscreen in a wide bezel with two large knobs flanking the display. AM/FM/Bluetooth and a USB port - no navigation, no CarPlay. The most common factory radio on lower trims.
RA3 - Uconnect 8.4A: standard on R/T Plus and many Scat Pack cars, optional on SXT Plus. 8.4-inch touchscreen with the row of hard buttons (Radio, Media, Controls, Climate, Phone, Apps, Nav) along the bottom. Nav button is present but inactive on screen unless the owner paid for the Mopar nav activation.
RA4 - Uconnect 8.4AN: standard on SRT 392 and SRT Hellcat, optional on R/T trims. Identical 8.4-inch bezel to the RA3, but the Nav button brings up a working factory map, and the unit displays HD Radio plus SiriusXM Traffic/Travel Link logos. RA4 cars usually carry the SRT Performance Pages app as well.
Quick visual check: small 5-inch display = RA2. Big 8.4-inch display with a 'navigation not activated' message = RA3. Big 8.4-inch display with a working map and HD Radio logo = RA4. Apple CarPlay/Android Auto did NOT exist on any 2016 Challenger from the factory - that arrives with the Uconnect 4C in MY2017.
Check the Display First - Serial Retrieval Without Tools
The method for 2016 Dodge Challenger is this:
The 2016 Dodge Challenger's retro-styled 2-door muscle coupe interior features the Uconnect 8.4" (RA3) touchscreen prominently in the cockpit. The serial number is available directly on screen via Dealer Mode.
Climate Button Method:
- Turn the ignition to ACC or ON.
- On the Challenger's wide center console, locate the Climate Up, Climate Down, and Front Defrost buttons beneath the 8.4" display. Press and hold all three at once for 5 seconds.
- Dealer Mode appears on the display.
- Navigate to: System Info → Radio Part Info → Serial Number.
Alternative: Hold Temperature Up (red) and Temperature Down (blue) together for 5 seconds to access Engineering Mode, then navigate the same menu.
Screen-Based Serial Lookup Method
2016 Challenger cars equipped with the 8.4-inch Uconnect screen include a hidden dealer/diagnostic menu that displays the radio serial number directly on the touchscreen, so the unit normally does not have to come out of the dash. The base 5-inch Uconnect (RA2) does not offer a documented on-screen serial procedure.
Uconnect 8.4 (RA3) and Uconnect 8.4N (RA4)
- Place the ignition in RUN/ACC and wait for the Uconnect screen to fully load.
- Press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST buttons together.
- Keep all three buttons held for roughly 7-10 seconds until the dealer/diagnostic interface opens.
- Open the radio or system info section to view the serial number printed on screen.
- Snap a photo of the screen so the characters can be copied across without errors.
Check the S/N by Pulling Out the Unit
If the serial number cannot be accessed via display, use the pull-out method.
Most Dodge Challenger factory radios include a sticker with the serial number printed on the casing.
Process details:
- Disable power.
- Gently detach surrounding dashboard trim.
- Release clips holding the radio.
- Slide outward to inspect the label.
Should Dealer Mode be unavailable on your 2016 Challenger, physical removal of the RA3 radio is necessary. The Challenger's wide, retro-style center console has a distinctive trim layout:
- Remove the center stack bezel – The Challenger's trim panel encompasses the 8.4" screen and HVAC controls. Insert a trim tool at the lower edge – the panel typically starts at the lower edge first.
- Unscrew the 4 Torx T20 bolts – These secure the radio mounting frame to the dash structure.
- Ease the radio forward – Pull the unit out enough to expose the serial label on the top or side of the unit.
The 14-character serial is on a barcode sticker. Cables can remain connected.
Locate Serial on Challenger's Radio Chassis
If the screen-based shortcut is unavailable - for instance on the base Uconnect 5.0 (RA2) - the printed chassis label is the next reliable source for the serial on a 2016 Challenger.
- Safety first: turn the ignition off, remove the key, disconnect the negative battery terminal, and wait a few minutes before touching wiring; avoid the yellow airbag/SRS connectors entirely and use plastic trim tools so nothing shorts or breaks.
- Tools you will need: plastic trim removal kit, Phillips screwdriver, small Torx bit set, flashlight.
- Pop the centre dash bezel free with a plastic trim tool, working slowly around the panel so the hidden retaining clips release without cracking the trim.
- Unplug the HVAC/climate control connector and the hazard switch from the back of the bezel before laying it on a clean cloth.
- Remove the four Phillips screws (two upper, two lower) that hold the radio cage to the support bracket.
- Slide the radio straight rearward and disconnect the antenna lead and the multi-pin power/data harness on the back of the unit.
- The serial number lives on a printed barcode/sticker label on the top, side, or rear of the radio chassis, alongside the part number and supplier markings.
- Photograph the label up close and double-check easily confused characters such as 0/O and 1/I before submitting the serial.

Typical Radio Serial Prefixes and Formats
Year Dodge Challenger Uconnect 8.4" (RA3) radios use these common serial formats:
T00AM– Harman VP2 Uconnect 8.4" (standard prefix)T00BE– Continental-manufactured versionTM9– Earlier Harman units
The Challenger's radio is designated RA3 (or VP2 with Alpine audio). Serial: 14 characters, e.g., T00AM394958584.
Note Do not mix up the serial (T00AM...) with the part number (P05064... or 68...) on the Challenger's radio label. Only the serial is needed to calculate the unlock code.
Standard Serial Number Patterns on This Radio
The factory head units fitted to the 2016 Challenger follow the standard Mopar/Continental serial pattern, with the prefix varying by supplier and Uconnect tier.
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 includeT00AM,TM9, andTQ1- or withA2Con Continental-supplied variants. - Usually runs as continuous letters and digits with no spaces or dashes.
Uconnect 5.0 (RA2)
- Usually carries a Mopar/Harman-style serial on the chassis sticker; the label printed on the unit itself is the authoritative reference.
- Always copy the serial exactly as printed and avoid guessing unclear characters.
Why Is the Radio Asking for a Code?
Owners of this muscle coupe encounter radio lockouts more than some other models because:
- Seasonal storage and battery drain — The Challenger is often a weekend or summer car, and months without use drains the battery enough to lock the radio.
- Battery replacement — standard battery service triggers the lock on any model year.
- Performance battery work — Owners who disconnect the battery for mods will trigger the lock.
- Used purchase — second-hand purchase without the prior owner's code means the code is needed right away.
The unlock code is permanently linked to the serial number and does not change.
Troubleshooting Common Radio Problems - Challenger 2016
If the Challenger's screen doesn't show after a battery event:
- Turn the ignition to ON (not ACC) and allow 15–20 seconds for the Uconnect system to load.
- Check the fuse box for the Challenger's radio fuse — a blown fuse prevents the display from powering.
- Tap the touchscreen once to trigger the code entry prompt if it hasn't appeared.
If the display stays dark, a blown fuse is worth checking first.
After three failed code entries on the Challenger's Uconnect, a 60-minute lockout activates and the screen shows "WAIT":
- Leave the key in the ON position — engine does not need to run but the key cannot be cycled.
- Wait for the entire 60 minutes.
- Cycling the ignition restarts the 60-minute wait.
Once the lockout clears, re-enter the code carefully.
Code rejection on the Challenger's Uconnect 8.4" usually means the wrong serial was used. The RA3 label shows both: the serial (T00AM, T00BE, or TM9, 14 characters) and the part number (P... or 68...) — the part number does not generate a code.
Confirm the serial via Dealer Mode and contact support for a free re-check if needed.
The 2016 Challenger's Uconnect 8.4" uses touchscreen-only input for code entry — none of the Challenger's factory radio buttons are involved. When "ENTER CODE" is on screen:
- Tap each digit on the virtual keypad on the 8.4" screen.
- The Challenger's Uconnect auto-confirms after the final digit — no confirmation button is needed.
If taps don't register, cycle the ignition and wait 30 seconds.
The Challenger's RA3 radio label shows multiple identifiers that are easy to mix up:
- Serial number — 14 characters, starting with
T00AM,T00BE, orTM9. This is what you need. - Part number — begins with
P05064or68. Not the serial.
Using Dealer Mode is the cleanest way: System Info → Radio Part Info → Serial Number. No tools required.
