Where to Find the Serial Number on your Grand Cherokee

The first step is to locate the radio's serial num.

Based on the head unit type fitted in your 2011 Grand Cherokee, the serial can be accessed either through the screen menu or by pulling the unit out and checking the label on the radio itself.

Follow the steps below to identify your serial the right way.

Factory Radios on the 2011 Jeep Grand Cherokee

The 2011 model year launched the all-new WK2-platform Grand Cherokee and rolled out the MyGIG-era radio lineup that Mopar shared across Chrysler, Dodge, and Jeep. Identifying which head unit is in your dash determines where the serial number is printed and how the security-code prompt is presented.

  1. Base AM/FM/CD (sales code RES) - Entry-level Media Center 130 single-CD receiver fitted to lower-trim Grand Cherokees. Small non-touchscreen monochrome display with hard buttons, CD slot, MP3/WMA support, and no Bluetooth or navigation. This was the highest-volume factory radio on the 2011 Laredo trim.
  2. MyGIG Media Center 430 (sales code RBZ) - Optional MyGIG touchscreen with a 6.5-inch color display, internal hard drive, USB, SiriusXM, and Bluetooth (where equipped). Has no Nav tile on the home screen and no Garmin splash at boot. Common upgrade on Limited trims for 2011.
  3. MyGIG Navigation 430N with Garmin (sales code RHB) - Same 6.5-inch MyGIG hardware as the RBZ but adds Garmin-based GPS navigation. The giveaway is the Garmin logo at boot and a Nav button on the home screen. Available factory option on 2011 Grand Cherokees.
  4. MyGIG Navigation 730N with NAVTEQ (sales code RHR / RB5) - Top-tier MyGIG nav radio with NAVTEQ maps and Harman Becker GUI, fitted to Overland and other higher-spec packages. Same 6.5-inch screen as the RHB but uses different navigation software (NAVTEQ instead of Garmin) and adds SiriusXM Traffic and Travel Link.

Quickest visual check: small non-touch display with a CD slot = RES; 6.5-inch touchscreen without a Nav icon = RBZ; 6.5-inch touchscreen with a Garmin boot splash = RHB; 6.5-inch touchscreen with a NAVTEQ-style map UI = RHR.

Screen-Based Serial Lookup Method

The method for 2011 Jeep Grand Cherokee is this:

The 2011 Jeep Grand Cherokee (WK2) was fitted with either a base CD radio or a MyGIG touchscreen (430, 430N or 730N). On the touchscreen units the radio displays its own serial on the Security Screen as soon as it asks for the code, so you do not need to pull it out:

  1. Switch the ignition to ON and wait 10 to 20 seconds for the radio to boot.
  2. The display opens Security Screen with Enter Security Code next to a keypad.
  3. Copy the 14 characters under Serial Number, such as T00AM0326T0528 or T00BE027470932. Enter it without spaces - that is the number we need for the code.
MyGIG Security Screen showing a T00AM serial number under Serial Number
T00AM example on the MyGIG Security Screen: copy the value under Serial Number.
MyGIG Security Screen showing a T00BE serial number under Serial Number
T00BE example on the same MyGIG Security Screen: the layout is identical, only the prefix changes.

The entry-level RES CD radio cannot show the serial on its small display - read it from the label on the radio chassis using the removal steps below. Do the same if the MyGIG screen never reaches the Security Screen.

Releasing the Radio to See the S/N on the Tag

If the serial number cannot be accessed on-screen, use the pull-out method.

Most Jeep Grand Cherokee original radios include a sticker with the serial number printed on the chassis.

Step-by-Step:

  1. Switch off the vehicle.
  2. Detach the dashboard frame surrounding the radio.
  3. Release the fasteners.
  4. Move the unit slightly out to access the label.

The serial number is usually located near the manufacturer sticker.

To extract the radio from the 2011 Grand Cherokee (WK2):

  1. Switch off the vehicle completely.
  2. Remove the large dashboard bezel around the radio and HVAC controls. The WK2's wide center stack trim has plastic retaining clips – start at the top or bottom edge and pry along the perimeter.
  3. Remove the four Phillips mounting screws holding the radio to the bracket.
  4. Ease the radio forward. The Grand Cherokee has decent clearance for removal.

WK2 Note: Certain Grand Cherokee trims have a larger climate control cluster below the radio — both come off together as one panel on most trims.

View Serial by Pulling Out the Radio Unit

On the 2011 Jeep Grand Cherokee (WK2 platform), a MyGIG touchscreen (RBZ, RHB or RHR/RB5) shows its serial on the Security Screen while it is locked, so check the screen first. Pulling the head unit to read the manufacturer label on the chassis is needed for the base RES single-CD receiver, or when the touchscreen stays dark. The removal procedure is essentially the same for every unit.

  1. Safety first. Turn the ignition fully off and remove the key. Disconnect the negative battery terminal and wait several minutes before working in the dash so any SRS / airbag capacitors can discharge. Avoid yellow airbag wiring and release every connector by its lock tab rather than tugging on the wires.
  2. Tools to have ready. A set of plastic pry/trim tools (or a small flat-blade screwdriver wrapped in painter's tape to protect the soft-touch finish), a 7mm socket with ratchet and short extension, a #2 Phillips screwdriver, and a small parts tray for the four chassis screws.
  3. Pop the receiver trim panel. The radio bezel on the WK2 Grand Cherokee is held by perimeter spring clips. Start at the bottom edge with a panel tool and work outward, freeing the metal retaining clips along the entire perimeter. There are several clips around the bezel, so move in small steps rather than levering hard at one point. Recover any clips that stay behind in the dash holes and re-seat them on the bezel.
  4. Disconnect bezel-mounted controls. Tilt the loose bezel toward you and unplug any harnesses attached to it (typically hazard switch / climate or display connectors), then set the bezel aside on a soft surface so the painted face is not scuffed.
  5. Remove the four 7mm chassis screws. The radio is secured to the dash sub-frame by four 7mm hex-head screws, typically one near each corner of the mounting cage. Remove all four and keep them together so they are not mixed with bezel hardware.
  6. Slide the unit out and disconnect. Pull the radio straight forward out of its opening, then release the locking antenna connector and unplug the multi-pin electrical harness(es) at the back of the unit.
  7. Read and record the S/N. The 14-character serial number is printed on a white or silver manufacturer label on the chassis (top, side, or rear depending on the unit), alongside a Chrysler/Mopar part number and a barcode. Photograph the label with your phone for a clear, zoomable copy and transcribe the value carefully - capitalisation matters and the digit zero is easy to confuse with the letter O.
  8. Reinstallation tips. Reconnect harnesses before sliding the unit back in; route the antenna cable so it does not get pinched; tighten the four 7mm screws snug but not over-torqued; align the bezel and press around its perimeter until you feel each clip seat.

Tips: for stubborn clips, work the trim tool in small increments rather than levering hard at one spot; warm cabin temperatures make the plastic more forgiving than a cold morning in the garage; and label the harness connectors if you plan to leave the radio out for any length of time.

Standard Serial Number Patterns on This Radio

Typical radios in the 2011 Grand Cherokee WK2 and where each one shows its serial:

  • MyGIG 430 / 430N (RBZ, RHB - 6.5-inch touchscreen, hard drive) - serial usually starts with T00AM or T00BE and appears on the Security Screen while locked.
  • MyGIG 730N (RHR / RB5, NAVTEQ navigation) - the same Security Screen; some units use TM9.
  • Base CD radio (RES, no touchscreen) - serial printed on the label only.

All of these serials are 14 characters long, for example T00AM0326T0528. What to ignore starts with P05064... or 68... - only the serial is used for the code.

Typical Serial Number Formats for 2011 Grand Cherokee Radios

Serial numbers on the 2011 Grand Cherokee's factory radios are typically 14 characters long and commonly begin with the letter T, printed on the chassis label together with a Chrysler/Mopar part number and a barcode. The exact prefix usually depends on which sales-code radio is installed.

RES (Base AM/FM/CD)

  1. Typically a 14-character alphanumeric string commonly beginning with T, followed by a family identifier and a production sequence printed on the chassis label. Treat any leading whitespace, dashes, or an S/N prefix on the label as formatting only - they are not part of the serial value you submit.

RBZ / RHB (MyGIG 430 and 430N)

  1. Commonly begins with T00-style prefixes such as T00AM or T00BE, followed by digits to make up the full 14-character string. These are the most common factory MyGIG units you will see in 2011 Grand Cherokees and are typically Mitsubishi-built.

RHR / RB5 (MyGIG 730N with NAVTEQ Nav)

  1. Commonly begins with TM9 followed by a numeric sequence to fill the 14-character format. These are the higher-trim navigation variants and are typically found on Overland, Limited 4x4 packages, and SRT-equipped cars.

Always verify the printed value against the chassis label - prefixes can vary between production runs and supplier batches, and an entry that is one character off will be rejected by the radio.

Radio Code Input Guide

After receiving 2011 Jeep Grand Cherokee unlock code from the serial, you're ready to reactivate the radio.

Some drivers hesitate at this stage because input methods can look different across radio versions, but it's usually easy.

When the radio shows dashed lines, it means the unit is waiting for the correct numbers.

Detailed Entering Instructions for Grand Cherokee 2011

To input the code on the 2011 Grand Cherokee's radio:

  1. Turn ignition to ON. The MyGIG touchscreens show the Security Screen; the base CD radio shows "CODE".
  2. Touchscreen models (MyGIG 430, 430N, 730N): Tap the number keypad on the Security Screen to enter each digit.
  3. Non-touchscreen (base CD radio): Press preset button 1 multiple times for the first digit, button 2 for the second, etc. Hold Enter/OK to confirm.

Warning: 3 incorrect entries trigger a lockout. Keep the radio running for approximately 60 minutes to reset.

Entering Process

Once you have the correct 4-digit anti-theft code for your 2011 Grand Cherokee's radio, entering it is straightforward, but you only get a limited number of attempts before the unit forces a cooldown.

  1. Limited Attempt Warning (read first). Mopar MyGIG units (and the base RES receiver) typically allow up to three attempts to enter a valid code. After three successive invalid entries the radio drops into a WAIT (LOCK) state and the display will read WAIT. To clear it, leave the ignition in the RUN position with the radio powered for a continuous 30 minutes (the vehicle may be driven during this time). After exiting the WAIT state the display returns to CODE and a valid code can be entered. Do not power-cycle the radio during the cooldown - it generally resets the timer.
  2. Power up. Turn the ignition to RUN (or ACC if your trim supports it) and wait for the radio to finish booting and show the CODE / ENTER CODE prompt.
  3. Entry on a MyGIG (RBZ / RHB / RHR / RB5) touchscreen. Use the on-screen numeric keypad to tap each of the four digits of your code in sequence. Once the fourth digit is shown, an OK / GO button becomes active on screen. Tap it to submit; a correct code clears the prompt and the radio returns to normal operation.
  4. Entry on the base RES (single-CD) radio. With the ignition in RUN and the display showing CODE, use the station preset buttons (1-4) to dial each of the four digits, then press the labelled enter/OK button to submit (or briefly hold the assigned preset, depending on the unit's labelling). The display returns to play mode when the code is accepted.
  5. If the code is rejected. Stop after the second failed attempt, double-check the code against your paperwork, and start a fresh entry from the first digit on the next attempt. It is much cheaper to take the 30-minute wait than to risk further escalation.
  6. Tip. Tap each digit deliberately - rapid double-taps on the MyGIG touchscreen can register an extra digit and inadvertently submit an incorrect entry.

Why Is the Radio Asking for a Code?

WK2 Grand Cherokees frequently experience radio lockouts because of:

  • Battery disconnect or replacement — the primary trigger on these older radios. Any power interruption activates the anti-theft.
  • Electrical service work — the WK2 has many electronic features and service requiring a battery disconnect locks the radio.
  • Aging battery failure — batteries in vehicles of this age fail without warning, which arms the anti-theft.
  • Used purchase — Grand Cherokees are popular used vehicles, and the code is often not passed on.

The unlock code is permanently tied to the radio serial and does not change.

Grand Cherokee 2011 Common Radio Problems

On a MyGIG touchscreen nothing has to come out of the dash: the serial is printed under Serial Number on the Security Screen while the radio is locked. Only the base RES CD radio has to be pulled to read the label. Look for:

  • Serial number - 14 alphanumeric characters, starting with T00AM, T00BE or TM9, for example T00AM0326T0528. This is what you need.
  • Part number - starts with P05064 or 68 on the label. Do not use.

These vehicles often go through multiple battery changes over their lifespan - note the serial somewhere safe the first time you see it and the next lockout takes a minute.

If the Grand Cherokee's radio does not show a code prompt after a battery event:

  • Check the ignition is in the ON position and wait 15–20 seconds for the radio to boot.
  • Check the fuse panel — fuse failure prevents the radio from powering on.
  • The WK2's tall center stack may have a slightly unseated radio connector — reseat the harness if nothing displays.

Code failure on a MyGIG or base Grand Cherokee radio almost always means the wrong serial number was submitted. Check your order against the value under Serial Number on the Security Screen (or on the chassis label of the base CD radio): 14 characters, most often starting with T00AM, T00BE or TM9. The part number (P05064... or 68...) does not produce a code.

Should the code fail, photograph the screen or the label and contact support for a free re-check.

After 3 failed attempts on a MyGIG or early Uconnect Grand Cherokee radio trigger a ~60-minute lockout. The screen displays "WAIT" or goes quiet. To clear the lockout:

  1. Keep the ignition ON — engine doesn't need to run, but the key must stay in ON.
  2. Do not turning the ignition off — the clock restarts from zero.
  3. After the wait, the "CODE" display returns.

How you enter the code on the Grand Cherokee WK2 varies by which radio it has:

  • Touchscreen (MyGIG 430, 430N, 730N) - Use the on-screen keypad.
  • Non-touchscreen (base CD radio) - Press preset buttons 1–4 to cycle each digit, then hold Enter/OK.

If unsure: a glass display you can touch means touchscreen entry; a button-only face means preset button entry.
