Door won't open

try this first, make sure all doors are locked. Insert door key in drivers side door lock and turn key left for 3-5 seconds then turn to the right with a little pressure. open door. Insert key in ignition and turn to on ONLY! wait at least 30 seconds, then turn key to start allow to idle for a few minutes. If problem persists, the remote is not functioning properly. contact a locksmith for reprogramming or replacement. A lock shop will be cheaper than the dealer! Hope this helps you!

NOOOOOO! Very easy to solve!!!!!
1.) Lock the car with the original key + remote control.
2.) open the car with the original remote control.
3.) Sit into the car, close ALL doors and windows.
4. Put in the ORIGINAL keys into the ignition and turn it right, until the dasboard lights go on.
5. Wait 10-15 seconds.
6. Take out the keys.
7. Leave the car and lock it with the original remote control.
8. Wait a minute or so.
9. open the car w. the original remote control.
10. Start your car and viola! Will start like a charm.
At least it happened to me with my 2006 cherokee.

IF NOT there is another method, one of these 2 will work!

Try Inserting the correct key in the ignition at least 3 times. Don't turn the key, just insert it-let it sit for 5 seconds and then remove-do this 3-5 times, then insert the key and attempt to start again

Hope it helps, BTW, the anti-theft immobilizer was working.

Below a schematic drawing how the anti-theft immobilizer works, just to give more insight.

I had the same problem with a Toyota truck, either the key is worn or the lock itself is, you can try slightly moving the key back and forth while turning it in the lock. Do not apply too much pressure or you'll risk snapping the key off. to fix the problem completely, I would try having a new key made, if that doesn't work, get new locks, have them keyed to match by a locksmith.

you can use the old method of a coat hanger and move it to either pull on the interior handle to open the door or push on the door lock button to unlock.sometimes a police officer can unlock it for you if they are not on a call as a public service,every place is different though.if you have a second key then you can get it to open the door.you can also call a shop to do a service call to unlock the car this will cost you a service call fee.if you have something like roadside assistance(CAA or such)they can do this also.the last thing is you can break a window and send a claim to your insurance company depending on your deductible.

only the dealer can repair this, the Body control computer must be programmed to the new lock cylinder, there is no way around this.

You can try calling a locksmith and see if they can get in. Locksmiths can use a tool to open the door by catching the rod inside the door frame. The last time I used a lock smith to open a door, it ran about $35.

I suspect once the battery issue has been resolved, you will need to reprogram the key fobs or figure out how to disable the alarm.

A little Costly, But contact a Locksmith to make you a New key from the Door lock or the Glove box lock,"If it's the same key"

Cost could be up to $150, Or as low as $45 an Hour.

A good locksmith Should be able to help in 30 to 45 min's

you can get a regular key from the dealer to just open your doors and not start the vehicle. It will cost about $5, but you will need proof of ownership and have a picture id.

Why are you taking out the old one. Check with any good locksmith. If your door key fits the ignition, you can easily remove a door lock cylinder and the locksmith can make you a new key!!! I'm pretty sure to remove your lock you need to turn it with the key in it (but you don't have one)

replace the lock yourself its easy cheap only thing you may have an extra key but hey
