How to Reset the Immobilizer on a Jeep Grand Cherokee and Reset Anti-Theftby David Clair
Some models of the Jeep Grand Cherokee are equipped with an immobilizer anti-theft system that disables the engine. The system is activated when something other than an authorized key is used to try to start the engine. Most models are also equipped with an alarm system as part of the security system. If something triggers the immobilizer or the alarm system, you need to reset and rearm the system.
Open the driver's side door. Close the other doors.
Press the power door-lock switch on the keyless entry fob.
Close the driver's side door. Leave all doors closed for about 16 seconds until the Vehicle Security Light on the instrument cluster stops flashing quickly. When the light flashes at a slower rate, this signifies that the system has been reset and rearmed.
