Is your 2005 Jeep Grand Cherokee key fob failing to unlock your doors or start your car remotely? Replacing a key fob can be costly, but programming a new or replacement key fob yourself can save you both time and money. This guide provides comprehensive instructions for programming your 2005 Jeep Grand Cherokee key fob, allowing you to regain full control over your vehicle’s keyless entry system. Whether you need to program the remote functions or the transponder chip, follow these straightforward steps to get your key fob working like new.
To program the remote functions of your 2005 Jeep Grand Cherokee key fob (lock, unlock, panic, trunk), please ensure you have at least one working remote. Unfortunately, if you don’t have a working remote, these DIY instructions will not be effective, and you will need to seek professional help from a locksmith, mechanic, or dealership for programming.
Here are the steps to program your remote:
-
Resynchronize Remote: Begin by pressing the LOCK button on your existing working remote five times, with two-second intervals between each press. This step helps to resynchronize the remote’s signal.
-
Ignition Cycle: Insert your key into the ignition switch and turn it to the RUN position. This is the position just before you would crank the engine to start. Wait for the ignition chimes to completely stop before proceeding.
-
Initiate Programming Mode: Take your working remote and press and hold the UNLOCK button for a duration of 4 to 10 seconds.
-
Enter Programming Sequence: While still holding the UNLOCK button, press and release the PANIC button on the working remote for one second. Then, release both buttons simultaneously. Listen for a chime, which should sound within 3 seconds to indicate that the vehicle has entered remote programming mode.
-
Program New Remote: Within 30 seconds of hearing the chime, take the new remote you wish to program. Press and release both the LOCK and UNLOCK buttons at the same time. Immediately after, press and release just the UNLOCK button on the same new remote. A chime will sound to confirm that the new remote has been successfully programmed. If you have additional remotes to program, repeat this step for each new remote within the same 30-second window, listening for a chime after each successful programming.
-
завершение Programming: Turn the ignition switch to the OFF position and remove the key from the ignition.
-
Test Remotes: Thoroughly test all programmed remotes to ensure that the lock, unlock, panic, and trunk functions are working correctly.
2005 Jeep Grand Cherokee key fob remote used for keyless entry and remote start systems, programming instructions provided.
For programming the key transponder/immobilizer chip (metal key portion) of your 2005 Jeep Grand Cherokee key, which is essential for starting the vehicle, there are different prerequisites and steps. This procedure is specifically for vehicles manufactured in the USA. Critically, you must possess two already working and programmed remote/keys to add a third key yourself. If you only have one working key and want to program an additional one, this DIY method will not work, and you will need assistance from a qualified locksmith, mechanic, or your Jeep dealership.

-
First Key Activation: Insert your first working programmed remote/key into the ignition and turn it to the ON position for 5 seconds. Do not start the engine. After 5 seconds, turn the key to the OFF position and remove it from the ignition.
-
Second Key Activation: Within 5 seconds of removing the first key, insert your second working programmed remote/key into the ignition. Turn the ignition to the ON position again without starting the engine. Observe the security light on your dashboard; it should begin to flash, and you may hear a chime within 10 seconds. After this, turn the key to the OFF position and remove it. Note that some 2005 Jeep Grand Cherokee models may only flash the security light without a chime.
-
Program New Key: Within 5 seconds, insert the newly cut remote/key that you wish to program into the ignition. Turn the ignition to the ON position (do not start the engine). The security light should flash again, and within 10 seconds, you should hear a chime (if your vehicle is equipped) and the security light should turn off. Once the security light goes out, the new remote/key should be successfully programmed. Turn the key to the OFF position and remove it.
-
Test Key and Remote: Test the newly programmed key to ensure it starts your 2005 Jeep Grand Cherokee and that all remote functions are also working correctly.
By following these instructions carefully, you can program your 2005 Jeep Grand Cherokee key fob and transponder chip, saving yourself the expense of professional programming, provided you meet the necessary conditions of having existing working keys or remotes.
