Why Did the Radio Lock and Ask for a Code?
The 2014–2018 Jeep lineup, radio lockouts are common because of:
- Battery disconnect or replacement — the most common trigger on all Uconnect 8.4" vehicles. Any power interruption locks the radio.
- Dead or drained battery — Jeeps used off-road can drain batteries faster, making it more likely the battery dies and triggers the lock.
- Blown fuse — fuse replacement or failure also triggers code entry.
- Used vehicle purchase — these are common in the used market, and the code is frequently not passed on.
Your code is tied to the serial number and never changes.
How to Find the Serial Number on Your 2017 Jeep Grand Cherokee Radio?
The first step is to find the radio's serial number.
Based on the head unit type fitted in your 2017 Grand Cherokee, the S/N can be accessed either through the display menu or by checking the label on the radio itself.
Below are the most common methods to identify your S/N quickly.
Identify Your 2017 Grand Cherokee's Factory Radio
The 2017 Grand Cherokee continues with the WK2 facelift radio family. The lineup is unchanged from 2015-2016 - same three Uconnect head units, same sales codes, same visual cues. Apple CarPlay and Android Auto have not yet arrived on this hardware; those came in with the next-generation Uconnect 4C platform.
- Uconnect 5.0 / RA2 - standard on Laredo and base trims. A 5-inch color touchscreen, no CD slot, no NAV button.
- Uconnect 8.4A / RA3 - optional on Laredo, common on Limited. An 8.4-inch landscape touchscreen with the capacitive Radio/Media/Controls/Climate/Phone/Apps row along the bottom. No Nav tile on the home screen.
- Uconnect 8.4AN / RA4 - same 8.4-inch hardware as the RA3 but with built-in Garmin navigation, HD Radio and SiriusXM Traffic/Travel Link. Standard on Overland, Summit and SRT, optional on lower trims.
Quick tell: 5-inch screen = RA2; 8.4-inch screen with no Nav tile = RA3; 8.4-inch screen with a Nav tile/map = RA4. The sales code is printed on the label on top of the radio chassis.
Fast Serial Lookup Using Radio Controls
These are the steps you need to follow for 2017 Jeep Grand Cherokee:
The 2017 Jeep Grand Cherokee uses the Uconnect 8.4" (RA3) touchscreen. You can find the serial number using Dealer Mode directly from the display:
Climate Button Method:
- Turn ignition to ACC or ON (no need to start the engine).
- Simultaneously press the Climate Up, Climate Down, and Front Defrost buttons for approximately 5 seconds.
- Dealer Mode appears on the 8.4" screen.
- Go to: System Info → Radio Part Info → Serial Number.
Alternative: On the 2017 Grand Cherokee, you can also try holding the Temp Up (red) + Temp Down (blue) buttons for 5 seconds to enter Engineering Mode as an alternative.
Fast Serial Lookup Using Radio Controls
For 2017 Grand Cherokees fitted with an 8.4-inch Uconnect, the radio supports a hidden dealer/diagnostic menu that displays the unit's internal serial number. Reading it on the screen is much faster than removing the radio.
Uconnect 8.4A (RA3) and Uconnect 8.4AN (RA4)
- Start the engine or place the ignition in RUN so the touchscreen is fully booted.
- Press and hold the driver's temperature UP, temperature DOWN, and front DEFROST buttons together for around 7 seconds.
- When the dealer/diagnostic menu opens, choose the radio-information entries near the top of the list - they list serial numbers, hardware/software revisions and similar identifiers.
- Note the full serial exactly as printed, including any letters at the start such as
T00AMorTM9. - Press Done, or cycle the ignition off/on, to leave the menu.
Uconnect 5.0 (RA2)
An equivalent on-screen serial-number readout for the 5-inch RA2 in this generation is not consistently documented. If the hidden menu does not show one on the RA2, use the chassis-label method instead.
Manufacturer Label Inspection
If the serial number cannot be accessed through menu, use the hardware method.
Most Jeep Grand Cherokee OEM radios include a tag with the serial number printed on the housing.
Step-by-Step:
- Turn off the vehicle.
- Remove the trim surrounding the radio.
- Loosen the fasteners.
- Slide the unit forward to access the label.
The serial number is usually located near the manufacturer sticker.
If Dealer Mode is blocked on your 2017 Jeep Grand Cherokee, this is how to take out the radio:
- Detach the center trim – Use a plastic pry tool to pop off the center stack bezel surrounding the 8.4" screen. Jeep trim pieces use sturdy friction clips.
- Unscrew 4 mounting bolts – Usually Torx T20 or Phillips screws.
- Pull the unit out – Pull carefully to reveal the serial label on the top or side of the chassis.
Cables at the back can remain plugged in while you photograph the serial number.
Pulling Out the Radio Unit to See the S/N on the Tag
When the on-screen method is not available - or the radio is locked at the CODE prompt and you cannot reach the dealer menu - the chassis label is the most reliable source for the serial number on a 2017 Grand Cherokee.
Safety first
- Turn the ignition fully off and remove the key fob from the cabin.
- Disconnect the negative terminal of the 12V battery.
- Wait several minutes before working near the dash so airbag circuits can fully discharge.
- Stay clear of yellow airbag wiring while pulling trim.
Tools to have ready
- Plastic trim/panel pry tools to release clips without marking the dash.
- A 7 mm socket with a small ratchet or driver for the four radio retaining screws.
- A phone or camera for a clear photo of the label.
Removal overview
- Beginning at a lower edge of the center bezel by the climate controls, gently pry the lower bezel section outward; it is held by retaining clips, not bolts.
- With the lower bezel free, undo the two screws now exposed and ease off the upper bezel that frames the radio.
- Pull the bezel pieces forward and unplug any small switch/HVAC connectors on the back.
- Undo the four 7 mm retaining screws now visible at the corners of the radio chassis.
- Slide the head unit out and unplug the main wiring harness, antenna lead and any USB/AUX cables.
Where the serial sits
- Find the printed label on the metal chassis - typically on the top or side face.
- Copy the long alphanumeric string next to the barcode, taking care with similar characters (O vs 0, I vs 1).
Tips
- Photograph the label before reinstalling so the serial is preserved as a reference.
- Reassembly is the reverse: connectors back on, four screws home, bezel pieces snapped in, then reconnect the battery.

Common S/N Formats Used on 2017 Grand Cherokee Units
The 2017 Jeep Grand Cherokee Uconnect 8.4" is made by Harman or Continental. Common serial number prefixes:
T00AM– Primary Harman prefix (VP2/RA3)T00BE– Continental modelTM9– Earlier Harman production
Radio designations: RA3 (base 8.4"), VP2 (8.4" with Alpine or Harman Kardon audio). Serial: 14 characters, alphanumeric (e.g., T00AM394958584).
Note Don't use the part number (starts with P or 68). Only the serial generates the code.
Serial Number Format Guide for 2017 Jeep Grand Cherokee
The 2017 Grand Cherokee could leave the factory with one of several Uconnect head units, each built by a different supplier, so serial-number formats vary by radio. The patterns below are the ones most often reported for this generation.
Continental-supplied Uconnect 8.4 (RA3 / RA4)
- Frequently start with
T00AMfollowed by a numeric string, for example a serial resemblingT00AM1234567. - The prefix is printed inline with the rest of the serial on the chassis label.
Panasonic-supplied Uconnect units
- Often start with
TM9followed by additional digits or letters. - This pattern has been widely reported on Panasonic-supplied Mopar radios from the 8.4 era.
Uconnect 5.0 (RA2) base radio
- Also carries a printed serial label, but the prefix can vary - copy the full string off the label rather than assuming a fixed pattern.
If the alphanumeric you read does not match any of these patterns, double-check that you have the serial line rather than the part number. The serial is usually the longest string on the label and is the one tied to the barcode.
How to Unlock a Jeep Grand Cherokee Radio After Power Loss
Vehicle radios use security codes dependent on the radio unit itself rather than the model or production year.
- Our lookup service works by matching your Jeep Grand Cherokee radio's serial number.
- Once the serial number is submitted, the system identifies the radio family and retrieves the corresponding code.
- Simply input the digits into the Grand Cherokee stereo.
- The online process is quicker and more accessible than visiting the Jeep dealer.
Radio Code Input Guide
Once you have the radio serial and generated the unlock code, the last part is entering it into your radio.
Jeep OEM units display a locked screen when ready for input.
The process is quick, but button layouts and confirmation methods may differ slightly depending on the radio version installed in your Grand Cherokee.
The Correct Way to Enter It
To enter the code on the 2017 Jeep Grand Cherokee's Uconnect 8.4":
- Ignition ON. The screen shows "ENTER CODE" or ----.
- Tap the touchscreen number pad for each digit of the 4-digit code.
- Radio unlocks automatically after the 4th digit – no confirm button needed.
Lockout: 3 wrong entries = 60-minute lockout. Keep ignition ON for the entire period. Do not turn off – it resets the timer.
In-depth Entering Instructions for Grand Cherokee 2017
Once the correct anti-theft code is in hand, entry on the 2017 Grand Cherokee is quick, but you have a strict attempt limit before the radio locks itself out.
Limited Attempt Warning
You only get three attempts. After three wrong codes in a row the radio enters a WAIT state and the screen reads WAIT. To clear it, the radio must remain powered with the ignition in RUN for a continuous 30 minutes. Cycling the key off does not bypass the timer.
Entering the code
- Turn the ignition to RUN or ACC so the radio powers up and shows the CODE / Anti-Theft prompt.
- On the 8.4-inch Uconnect (RA3/RA4), tap each digit on the touchscreen number pad.
- On the 5-inch Uconnect 5.0 (RA2), enter the digits using the preset (1-6) buttons in sequence.
- Confirm with the OK/Enter on-screen control or the equivalent hardware button.
- When accepted, the radio returns to the normal home screen and audio resumes.
If it does not unlock
- Stop after the second wrong attempt and re-verify the serial number you used to obtain the code.
- Make sure no leading letters or trailing digits were dropped from the serial.
- If
WAITappears, leave the radio powered for the full 30 minutes before retrying.
Understanding Unlock Issues with Your Grand Cherokee
A wrong-code message on the Uconnect 8.4" most often indicates a serial number error. On the Jeep Uconnect radio label, you'll find two key identifiers: the serial number (T00AM, T00BE, or TM9, 14 characters) and the part number (P... or 68...). Only the serial is used for code generation.
A reliable approach to confirm the serial on this 2017 Grand Cherokee is through the on-screen Dealer Mode rather than reading the label. Reach out for a free re-check if the code was rejected.
If no "ENTER CODE" screen appears after a power interruption on the 2017 Jeep Grand Cherokee:
- Verify that the ignition is in the ON position — the radio requires full ignition ON — and wait 15–20 seconds for the system to initialize.
- Check the radio fuse — a failed fuse will prevent the radio from powering on.
- Some Uconnect 8.4" units may need a screen tap to trigger the code entry screen after startup.
If the screen stays black, the fuse panel is the primary thing to inspect.
After 3 wrong attempts, the Uconnect 8.4" triggers a 60-minute lockout and displays "WAIT" or "LOCKED". To get through the wait:
- Do not turn the Jeep off for the full 60 minutes.
- Turning off the ignition adds more wait time rather than helping.
On Jeep models from this era, the lockout timing is consistent across all model variants. Once the wait ends, re-enter the code carefully.
The Uconnect 8.4" (RA3/VP2) on the 2017 Jeep Grand Cherokee uses a touchscreen number pad exclusively — no physical preset buttons are involved in code entry. When the locked screen appears:
- Press each digit on the on-screen number pad.
- The radio auto-unlocks after the 4th digit — no confirm step is needed.
Should taps not register, cycle the ignition and wait for 20–30 seconds.
The fastest way to retrieve the serial on the 2017 Jeep Grand Cherokee's Uconnect 8.4" is Dealer Mode: hold Climate Up + Climate Down + Front Defrost for 5 seconds, then go to System Info → Serial Number.
- Serial number — 14 characters, beginning with
T00AM,T00BE, orTM9. This is the one to submit. - Part number — starts with
P05or68. Not the serial.
The on-screen method is more reliable than the label and avoids the chance of confusing similar-looking characters on a printed sticker.
