I don't think your vehicle has an airbag system, but please be certain if it has I would refer you to a manual for the proceedure to discharge SRS system before you start. Some local libraries have manuals that they will let you look at and photo copy. You will need a good quality steering wheel puller, and snap ring pliers and a tool to remove the locking ring retainer and to reinstall it. All you need to do is pull the horn ring (look at the back of the steering wheel) remove the screws that hold horn pad on. Next loosen the steering wheel nut do not remove at this time this is left on to prevent you from getting a steering wheel in the teeth when it pops loose, (possibly). Next check to see the locater marks on the column shaft and the wheel note position and mark if necessary. Do not use a hammer to pound on shaft of column it WILL damage the shaft! Use steering wheel puller tool to remove wheel. Next use the lock plate removal tool to depress and release pressure on retaining clip holding plate on remove plate. You may have to pull turn signal switch out of the way by removing the handle and retaining screws. Now you will see a plastic clip that holds two brass comtacts carefully move the top plastic release clip down to release and remove small contact assembly. You should be able to see a square notch in front of the mechanical key lock mechanism. With battery disconnected move cylinder to on position and slide out assembly. Slide new assembly in place and try back to lock position and remove key. Reverse order to assemble.

Can my key be reprogrammed in the ignition


The electronic key which you have only need to programme once, then it will work till get faulty not necessary to re programme there are only one way to re programme, it's only can do with new electronic ignition switch replacement so if you replace new ignition switch insert your key in it and it will take few minute for programme it take all the programme automatically then you can turn the key and start the car,
If you don't have replace the ignition switch but key is not working it's faulty either key or electronic ignition switch, if you have any other additional key if the car start with that key it's very clear it's faulty your key which is not working give me more details do you have the other key and only not working one key like that, however first replace the battery for your key and try if not work put a comment i will give you more details,

I have one key for the doors and another for ignition


Obviously the car was either in an accident and had the door(s) replaced with ones having locks not matching the ignition or the ignition was replaced and doesn't match the door keys. I'd go further and guess that it was the ignition that was replaced since you 1 key for the doors and a 2nd key for the ignition.

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.

I have a 98 dodge caravan and when i put the key


You may have to get a new key cut if the tumblers in the ignition lock are not being lined up to unlock the ignition. If the key's was bent in the ignition lock, the ignition lock may be bad and need to be replaced with a new ignition key. Try replacing the ignition key's first, but if you have a spare key. Try that first and if the spare key's don't turn the ignition lock, then you may have to replace the ignition lock. Good luck and keep me posted. oh and try moving the steering wheel left to right as you try to turn the ignition lock.

How to get key out that is stuck in ignition


Remove steering column shroud(cover)and tap ignition barrel with small hammer while twisting key backwards and forwards,also turn steering wheel backwards and forwards sometimes this is enough to release key as the locking pins in barrel and the steering lock pin do sometimes jam.You will have to remove steering column shroud to replace ignition barrel if tapping/hitting it doesnt work anyway so its not a wasted effort.Good luck,let me know how it works out
