    I have this same problem, just got a 2006 H3, and when locking with factory key it started. Dealer says its a remote starter that came on the vehicle, but i have no idea how to use it. If i hit the lock button more than a couple times it starts up. Does anyone know more about this type of remote starter so i can use it without randomly trying to start or stop it.... Any info is appreciated.

Try pressing "Lock" twice or hold "Lock" and "Unlock" together.

    It is a remote start option. If you hit lock 3 times from outside the vehicle it will remote start, hit it once more and it remote shuts off. If you do remote start it, just press unlock, get in the car, put the key in the ignition and put to run (not start). As soon as you touch the brake the whole system goes into normal mode.

    Mine is a 2005 H2 and the sytem works like a champ.

I have a Crime stoppers, remote starter. Original key fob will not unlock or lock the doors. Only remote starter to lock and unlock doors, having to carry both is very cumbersome. HELP


You either have the CS system on your car or you have it professionally removed which is what I would do.

If you install a product like this on your car which controls the central locking as well you won't be able to use the stock key fob for unlocking because the system is now programmed to the CS system.

Mustang alarm


Ford sold a Ford branded alarm through the parts department. These sometimes were a dealer installed option on new cars. Mine would randomly stop responding to the remote and I would have the same symptoms as you describe. I had it removed and the original equipment factory system still worked. Be warned, if you have the Ford "accessory" alarm, your key fobs (remotes) are different and the method to program them is different from what you will read online. You can tell if you have the system by looking at your key fob. The standard Mustang key fob is a 4 button (lock, unlock, panic, and trunk). The accessory alarm uses a 3 button remote and clicking unlock twice would pop the trunk. I really wish I had a picture of the remote because there are 3 button Ford key fobs for cars without a trunk release although I don't think you should have one on a Mustang. Long story short, if you have the accessory alarm, you can solve your problem by having it removed but you will need new 4 button key fobs to remotely lock/unlock your doors

2007 gmc yukon denali wont unlock w/ keyfob


Check the buttons.. I have an 06 Grand Prix with the Remote starter on the top and it seems that the conductor on the buttons worn out.. Take the keyfob apart, pull the rubber buttons off the chip, lick your finger and touch the place where the unlock (right side of the fob) would be. That should unlock your doors. I just did it with mine. I would just buy another fob on ebay and change the buttons out.. Hope this works

Key fob remote start issues


You need to get one that works on the same wide range frequency as the reciever in the car, and then it's a simple matter of opening both the new and old fobs, and matching the fine frequency settings by putting the little switches inside where they should be according to the old fob's switches. If there are no switches in the old fob, it's preset and there's not much you can do about it.

Dealer install remote starter bypasses kill switch


1) remote starter was not hooked up to the factory arm wire
2) trunk release was programmed to disarm factory alarm before popping trunk
3)parking light wire on remote starter was not hooked up
4)disarm wire from remote starter was not hooded up
5)this is not normal and they should fix the problem or have it done by some one else and have them pay for it, how much did they charge,
Bring it over I'll fix it right and not charge overpriced amount
