Our jeep liberty won't start. the battery will not turn over when we try to jump it. all lights, radio, inside lights turning lights work. The electric key will not lock it unless it is used manualy. what do we do? we have had the jeep for 20 months with no problems until now. what can we do. sincerely, Kathy Mahr

See that? Every once in a while I'm right!!! Reason is that the starter draws far more than anything else in the car. Lights and radio can easily be run by an otherwise ineffective battery, but when loaded (starter draws a bit less than 200amps), the battery will fall flat on its' face! When you jump it, the car is running off the alternator and seems to be OK, till you turn it off again.

Testimonial: "AWESOME, RIGHT IN THE MONE. SAVE ME $260.00 and a lot of headaches."

THEFT system is armed; check the disarm procedure in your Owners Manual.

If this isnt solve it, could be that you need to re-synch your antitheft security module.
