Lost your key fob or need to program a new one for your 2005 Jeep Grand Cherokee? You’re in the right place. Programming your key fob at home can save you time and money compared to dealership visits. This comprehensive guide will walk you through the step-by-step process for programming both the remote functions (lock, unlock, panic, trunk) and the transponder chip for your 2005 Grand Cherokee.
Programming Your 2005 Jeep Grand Cherokee Key Fob Remote
This section focuses on programming the remote control functions of your key fob.
Important Note: To use these instructions, you must already have at least one working key fob remote. If you don’t have a working remote, you will need to visit a locksmith, mechanic, or dealership for programming.
-
Begin by resynchronizing the remote by pressing the LOCK button five times, each press spaced approximately two seconds apart.
-
Insert your key into the ignition switch. Turn the ignition to the RUN position. This is the position just before you would crank the engine to start. Wait for the ignition chimes to stop sounding.
-
Take your working remote and press and hold the UNLOCK button. Continue holding the UNLOCK button for a duration of 4 to 10 seconds.
-
While still holding the UNLOCK button, press and release the PANIC button on the working remote for one second. Release both buttons simultaneously. You should hear a chime sound, indicating that your Jeep has entered remote programming mode. Allow up to 3 seconds for the chime to sound.
-
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, then immediately press and release just the UNLOCK button again on the same 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. A chime will sound after each successful programming.
-
Turn the ignition OFF and remove the key from the ignition.
-
Thoroughly test all programmed remotes to ensure they are working correctly, checking the lock, unlock, panic, and trunk functions.

Programming the Transponder Key for Your 2005 Jeep Grand Cherokee
This section details how to program the transponder chip within your key, which is necessary to start your 2005 Jeep Grand Cherokee.
Important Notes: This procedure is specifically for Jeep Grand Cherokees manufactured in the USA. Furthermore, you must have two already working and programmed remote/keys to add a third. If you only have one working key and want to program a second or third, this DIY method will not work, and you will need professional programming services.
-
Insert your first working programmed remote/key into the ignition. Turn the ignition to the ON position for 5 seconds. Do not start the engine. Turn the key off and remove it from the ignition.
-
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, do not start the engine. The security light on your dashboard will begin to flash, and you should hear a chime within 10 seconds. Note that some 2005 Grand Cherokee models may only flash the security light without a chime. Turn the key off and remove it.
-
Within 5 seconds of removing the second key, insert the new, uncut remote/key you wish to program. Turn the ignition to the ON position. Do not start the engine. The security light should start flashing, and within 10 seconds, you should hear a chime, and the security light should turn off. Once the security light goes out, the new remote/key should be programmed. Turn the key to the OFF position and remove it from the ignition.
-
Test the newly programmed key to ensure it starts your 2005 Jeep Grand Cherokee and that the remote functions are also working as expected.
By following these instructions, you can successfully program your 2005 Jeep Grand Cherokee key fob and transponder chip. For replacement key fobs and remotes, visit Keylessentryremotefob.com for a wide selection.
