Can I install a motor from a 2002 Impala in a 2004 Chevy SS?


You can, but you will need to bring a lot of the donor car components with and also bypass the security system if you intend on ever starting it.

Were is my security system located at in my 2004 Mitsubishi Galant


It is integrated in your entire electrical system of your vehicle. the only way to bypass is to get an aftermarket alarm with a bypass module which will require an additional ignition key (which is inserted into the bypass module).

Could anti-theft system d mustang cause car to shut off while driving?


Hi, im a retired ford tech, with alot of experience on ford anti theft . Now if you are asking about a built in oem factory anti theft, your not going to be able to bypass it. Now to answer your question, I would say your factory anti theft IS NOT causing your issue. It will make it unable to start,it doesnt kill anything else.

How do I bypass the theft system on 98 mustang GT conv.


You have the original key? If you don't, then save up to get t to a dealer and have the lock put in and have it reprogrammed. there is no bypassing a security system. Even places that claim this, all they do is bypass part of it. Like the key. Fords are different. They car has to be programmed to the key. Instead of the key programmed to the car.

MY 2004 CHEVY CAVALIAR WILL TURN OVER BUT WONT RUN AND THE INJECTERS ONLY SPRAY EVERY NOW AND THEN PLEASE HELP!!!


You are most likely experiencing a failed or failing Antitheft security system. Gm has had issues with this system since they first installed them in the early 80s. Contrary to what others may tell you, this system CAN be bypassed and eliminated. People will tell you that it is impossible, or even worse, illegal. This is simply not true. It is your vehicle and you can do whatever you want to your vehicle. This site has a lot of information and can help you beat this problem for far less than the $1000 dealer quote.

2004 mustang won't start because of anti theft system


Did you check the battery of the car (maybe loose cable)? but if it just happen suddenly, it might be your altenator that wasn't charging your battery. I think once there's enough power gone through the car then your anti-theft system should work as normal again.

My 2004 impala has full powere but won't start no


When it doesn't start, is the security light and maybe the battery light flashing?

If yes, it's probably the PassLock security system. I just bypassed mine on my 2002 Impala. There are several websites with information and possible solutions; including spending several hundred dollars at the dealer, to a do-it-yourself bypass for a couple dollars.

The best source of information I could find was:
http://www.bergerweb.net/grandamsecurityfix.htm
There is lots of good information there.

What wire do I cut to bypass the passlock on my 2004 alero


You Cannot cut any wires to bypass on this system. The passlock security needs to see a valid key in order to have the PCM enable the fuel and Ignition. This system is complex and cannot be bypassed with the cutting of a wire.
