Confirm Your Radio Model
Line up the design, controls, display and features listed below with your factory-installed radio - the Chrysler REJ Alpine is easy to identify once you know what to look for.
How to spot it:
- Centre-stack 6.5" touchscreen
- REJ printed on the factory label
- Label serial opening with TQ1AA, TT1AA, TH1AA, THAAA, TCAAA
You most likely have the Chrysler REJ Alpine if:
- the chassis label carries the REJ sales code
- the serial on the label starts with TQ1AA, TT1AA, TH1AA, THAAA, TCAAA
- it came in a car from the 2008-2013 range
- the screen is the 6.5" touchscreen fitted to the Alpine
REJ part numbers carry the P05064191, P05091508 and P82208905 prefixes - the P82208905 range in particular is a Jeep-MOPAR-only service number. If your part number begins with P05064247 or P05064248 you have a Harman REZ, not Alpine REJ.
About the Chrysler REJ Alpine
The Chrysler REJ Alpine is an original factory-installed head unit developed for selected Chrysler vehicles. Designed to provide reliable audio playback and vehicle integration, this unit may also offer Bluetooth connectivity, touchscreen controls, CD/DVD playback, navigation or multimedia support, depending on the exact configuration.
REJ Alpine is the Jeep-specific Alpine-audio MyGIG variant - 6.5-inch touchscreen MyGIG hardware paired with the Alpine premium amp package and tuning specifically for Jeep cabins (Grand Cherokee WK, Commander, Wrangler JK Sahara/Rubicon). Audio bias favours the front-stage surround used in those vehicles.
Chrysler used the Chrysler REJ Alpine on selected models produced between 2008-2013, typically alongside the Alpine multimedia platform. It is one of the factory units most often seen from that era.
Features you may find on the Chrysler REJ Alpine:
6.5" touchscreen
AM/FM radio
CD playback
AUX and USB input*
Steering wheel control support
Anti-theft security code
*Availability depends on the vehicle configuration.
As with other Alpine factory units, the Chrysler REJ Alpine locks itself when power is lost. After a battery disconnect or a workshop visit the screen will ask for the original security code before any audio returns.
Background on the platform itself is published by Alps Alpine, the unit's manufacturer.
Locating the Chrysler REJ Alpine Serial Number
The code is generated from the radio's own serial number, so that number is the only thing you need before ordering. It is printed on the chassis label of the unit itself, not in the vehicle documents.
On this unit: Top of the chassis label, near the rear edge. On Wrangler JK the radio bezel pulls forward with clips only (no screws on the face); on Grand Cherokee WK there are two 7mm bolts at the bottom corners of the trim. No on-screen serial display while locked.
Getting to the label:
- Bring the radio out of its slot; release keys do it in a minute and nothing needs disconnecting.
- The serial is on the chassis sticker, usually right next to the barcode - copy it down.
- Type it into the form exactly as printed, without spaces.
The sticker that carries the serial
Typical Ways a Chrysler REJ Alpine Gets Locked
The lock screen almost never appears out of nowhere - one of these four situations is behind almost every locked Chrysler REJ Alpine we see.
A repair cut the power
Alternator, starter or fuse-box work usually means disconnecting the battery - and the radio arms its anti-theft as a side effect of the repair.
You bought the car second-hand
No handbook, no code card, seller unreachable - none of it matters. The radio's own serial number carries everything needed to calculate the code.
A battery swap
A new battery - or a flat one after the car stood over winter - cuts power to the radio, and the anti-theft system arms itself the moment power returns.
A second-hand radio
A radio from a breaker or an online sale comes with its own serial, so it needs its own code - read the label on the unit you fitted.
All four roads lead to the same fix - read the serial off the unit, enter it above, and the original code arrives instantly.

How to enter your Chrysler REJ Alpine code
It takes less than a minute once you have the four digits.
- Give the radio power - key to accessory is enough - and wait for the code prompt.
- The screen shows a numeric keypad for the four digits.
- Punch in the four digits, first to last.
- Verification happens by itself once the fourth digit is in.
- The security screen disappears and the unit returns to normal operation.
If something goes wrong
The screen shows a wait timer
The timer is the radio guarding itself after failed entries - power on, patience, then try again. Three wrong codes triggers a 60-minute "WAIT" countdown. The timer counts down only with 12V applied. The correct code clears the lock permanently until the next power loss.
The serial is hiding from you
Nothing on the car's menus shows it - the number lives on the radio's own label. Top of the chassis label, near the rear edge. On Wrangler JK the radio bezel pulls forward with clips only (no screws on the face); on Grand Cherokee WK there are two 7mm bolts at the bottom corners of the trim. No on-screen serial display while locked.
It is asking for the code a second time
By design, every loss of power resets the anti-theft lock. Battery disconnect, dead battery, jump-start failure, or removal of the radio during dash service.
This radio looks like several others
A few models in this family share the same face, so the label is what settles it. REJ part numbers carry the P05064191, P05091508 and P82208905 prefixes - the P82208905 range in particular is a Jeep-MOPAR-only service number. If your part number begins with P05064247 or P05064248 you have a Harman REZ, not Alpine REJ.
Save the code: it stays valid, so the next battery change costs you nothing.
