SOURCE: 2008 jeep liberty navigation safety disable question

Can't be done. All the safety items are controlled by the ECM.
If the ECM senses the car moving via the speed sensor, it will disable the nav. To disable the safety would be to disable the computer and the car will not run.

SOURCE: 2002 jeep liberty Turn key switch makes loud

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.

SOURCE: Jeep liberty 2002.....ignition key lock

Most commonly it is the key is worn out. If you have a spare key or your current one is not too badly worn, have a copy of it made and try it in the switch. You will have to have the copy key "coded" so it will disable the anti-theft system in order for the engine to start. If the new key doesn't fix your problem, you will have to replace the tumbler assembly.

SOURCE: My Grand cherokee is not starting

If anyone has this problem also where you start your Jeep and it dies in about 2 seconds and the key symbol lights up on your dash I can help. I had this problem yesterday after jumping the battery, I had the correct key but it wouldn't read it. I had a locksmith come out and if you take off the steering column plastic there's a small black module in the column behind the key switch. Unplug that module for 5 minutes and it will reset. My Jeep started up right after. You MUST have the correct key though, mine is gray not sure about other years.

Duplication of keys may
be performed at an authorized dealer (or locksmiths) or by using the
Customer Key Programming procedure.

DIY, takes 1 key , good, called a valid key, in the below text.
You can program new keys to the system if you have two
valid keys by doing the following:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chime
will sound and the SKIS indicator light will begin to
flash. Turn the ignition switch OFF and remove the
second key.
4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound. The SKIS indicator
light will stop flashing, turn on for 3 seconds; then turn
off.
The new Sentry Key has been programmed. Repeat this
process to program up to a total of 8 keys.

Possible solution - This happened to me and my battery was dead in my key fob and also I needed an ignition switch because a piece on it was broken which therefore wouldn't turn to start the engine.

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....


have a load test done on the original battery as it appears that you have a shorted cell that is draining all the power from the jump battery.

I have an 08 Jeep Liberty that has a remote starter on the key. I tried to unlock the car with the remote, however, that didn't work, so I unlocked the car with the key. The alarm went off, I tried pushing...


Sounds like you have a key without the chip in it. Replacement keys without the chip will only unlock the doors and will activate the theft alarm when you start the vehicle.
