How to disable the passkey in my buick my car runs for a little while then shuts down won't start back for a few minutes security light on steady tried relearn process did not work any ideas how to by pass it not worried if someone tries to steal it it is a buick for gods sake not a rolls royce
I wonder how people have got so lame, The op asked how to disable passkey 3 and it never fails you always get a bunch of clowns telling him everything but what he asked for, or better yet advising him on what he should do. all the while they should have not said anything because they are real real close to mental retardation. he asked how to disable it retards,
your not gonna like my answer because its is expensive. you have to buy hp tuners or efi live and then you have to buy a license. then you can simply turn off security.
I have yet to find a cheaper method if you find one i would like to know as well.
Pull the computer, send it to a remanufacturer (www.flagship1.com) They can disable it $$128.00

How about actually FIXING it? It's really easy. There is NO way to disable PassKeyIII unless you know how to rewrite the software code. If you could disable it, they wouldn't call it anti-theft.

they have had alot of problems with key switches in that model that is where i would start
SOURCE: Car wont start-security light on-passkey issue?
if the security light is on it could be the ign lock cylinder, it has two small wires attached to it and one may be broken and are the keys the ones that came with the vehicle

man these buick dealerships are making a killing nowadays, the keys have a chip in them that helps a sensor in the steering column recognize that those are the right keys for that car, it's an anti-theft device that sometimes backfires, usaully the culprit is a damage chip in the key, because keys get thrown around and mashed up with other keys in peoples pockets, the key it self is not cheap but it is cheaper than replacing steering column. Get a new key and see if that helps, they should have provided you with a new key if they replaced the steering column and the sensor inside of it. I think dealerships aren't making enough money selling cars in this economy and are making frivolous repairs that don't help fix problems and charge a lot of money in the process
SOURCE: ignition will not start car. i think it may be passkey problem.
if security keeps blinking than what you have is a bad ignition switch, there is a wire built into the switch to recognise the passkeyand what happens over a period of time the wire will break internally.
When replacing this if doing yourself be carefull when removing and installing new one.After installation you will have to have the key recoded by using the dummy key that comes with the switch.
Good luck and please rank this solution, if I can be of any other help, please let me know. Thank you for using fixya.com
