Hello everyone. I am having problems with my key FOB working intermittingly. I have noticed that when getting out of the Jeep if I hit lock on the key FOB before closing the door it will lock every time. If I close the door, it will only lock 10% of the time. Do you know what can cause this?

Key FOB or car battery? I have replaced both of my key FOB batteries and they operate the same.

Ha! I was just about to start a thread and saw this, so I'll join in too if I may.

I have a UK version JK Wrangler, 2008 model year that I've had from new - & love.

Recently - in the last 6 months - both key fobs have been intermittently failing despite new batteries. My local Jeep dealership had it in for 5 weeks and basically couldn't fix it and told me the ECM module was no longer available from Jeep so I just had to put up with it or scrap it. Roll on a few months, and I now find my Jeep is locked (with the fob) and whilst I can unlock the doors with the keys, of course the alarm goes off and I have no way to stop it!!

This sounds like the dreaded SKIM/ECM problem for which I know of no fix. Can anyone suggest a way of (i) turning off the alarm (ii) some UK based Jeep specialist who can sort out the ECM? It seems in the States these are common but not here in the UK.

I should also add that when I can get into the Jeep I can start it but the immobilizer kills the engine after 3 secs or so.

Thanks.

D.

Bad form replying to my own post but after leaving the Jeep on charge - even though the battery claims to be charged, this morning the zaper worked, which is hasn't done every day for the last week. I hate intermittant faults and I can't trust the Jeep not to lockup on me miles from home at midnight.. Grrr...

For what it's worth, mine seems OK and at £200 GBP or so for a new battery I'm reluctant to take a punt on changing it.. So frustrating!!
