Imobiliser problem I own a 94' Mk3 Golf TDI, which has been stood for few months and battery has now gone flat. After charging the battery, I've found that the Remote Central Locking will not open the car, or turn off the Immobiliser or alarm. Central locking works with Key, but the engine will not start because the immobiliser is de-activated only with the Key Fob. I've replaced the batteris in the Key Fob / remote, and it appears to work, but the car just will not register anything from Fob...

I have a 06 Monte Carlo and my key fob is acting up. When the car is running, or when the door is open the key fob will work. But after the car is off or the door is close for a few min the fob will no longer work. I can not unlock, lock, or open the trunk. It has also been telling me to replace the batterie in remot key. I have replaced it and still have the same problem. Is it just time for me to get a new fop or is it something worse.

Problem with 2007 Ford Focus. Battery regularly runs down because digital display screen stays illuminated on dashboard console even when engine has been disengaged and powered off. May be linked to faulty key fob. Dealers have said that ignition has built in key which must be replaced with ordinary key barrel and key. Have you ever heard of this problem before? Is it common in this model? Is it a manufacturing fault?

2009 nissan murano intermittently does not recognize the key fob. Sometimes the door will not open by pushing the button on the door handle, sometimes it unlocks and then gives me the NO KEY indicator on the dash and the brake is hard and will not start. I have to get the key fob out and lock and unlock the doors a few times and then it recognizes it. Anyone else having these issues? Our Nissan dealer can't get it to fail when we leave it there for a day and will not try to fix the problem.

My original key fobs quit working on my 2005 GMC Yukon SLT. I changed the batteries with no positive result. I next replaced the key fobs and followed the programming. This worked for a couple of months and now I am back to my orginal problem even after attempting to reprogram the fobs. I believe my receiver module may have gone out and I am trying to determine its location within the vehicle so as to replace it.

It sounds as though your your vehicles code got scrambled. I doubt it was anything you did, its odd that it would simply quit working so suddenly. I know of no way to re-sync the Fobs to the car, that will likely have to be done By the dealer. Sin ... Dodge Challenger
