Manufactured by the Jeep division of Chrysler, the Jeep Grand Cherokee is a mid-sized sports utility vehicle that has been in production since 1993. Newer model Jeep Grand Cherokees use a keyless entry system known as Sentry Keys. A Sentry Key is a traditional car key attached to a programmable keyless entry fob. Once your Sentry Key fobs are programmed, you can use them to lock or unlock the doors of your vehicle by pressing the "Lock/Unlock" button on the fob.
Insert the first Sentry Key in the ignition cylinder of your Jeep Grand Cherokee. Turn the ignition to the "On" position for between three and 15 seconds. Turn off the ignition and remove the first Sentry Key from the ignition cylinder.
Insert the second Sentry Key in the ignition cylinder and turn on the ignition. Wait for a chime to sound and for the vehicle's lights to flash. Turn the ignition to the "Off" position and remove the second Sentry Key from the ignition cylinder.
Insert an un-programmed Sentry Key in the Jeep Grand Cherokee's ignition cylinder. Turn the ignition to the "On" position within 60 seconds of inserting the Sentry Key. Wait for a chime to sound and for the lights to flash before turning the ignition to the "On" position again. Wait three seconds before turning off the ignition.
Repeat the process to program up to eight Sentry remotes for your Jeep Grand Cherokee.
You cannot program additional keyless remotes for your Jeep Grand Cherokee without the two original Sentry keys. Contact your local Jeep dealership or service centre for more information.
