your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your buick dealer to get a new one,they are programmed for each car only,you cannot bypass it.

2003 ford ranger theft light blinking and won't start


the anti-theft has been activated and needs to be reset.you may have to get it to a shop that has the tools to do this or go to the dealer to get it done.did you use a key that was cut as a spare and doesn`t have a chip in it.this usually can cause this.also if the wires at the switch break it can activate the anti-theft system.

2003 envoy pulled into driveway,turned off engine,went out 30 minutes later and no start.replaced battery.security light comes on.still no start. any suggestions?


Hi and welcome to Fixya!

Anti theft deterrent may have been triggered. As a first course of action please perform the following.

- turn the key on ON and OFF position for 10 times but don't crank the engine
- on the 10th time let it on ON position for 10secs. then press the remote lock unlock button and wait for it to respond.
- once the lock goes up and down you may try to start the car.
- this procedure is for the reset of the anti theft and if it doesn't work I strongly suggest that you take it in to the dealership.

Hope this helps and thank you for using FixYa! Have a good one!

I have a 2003 Envoy. The vehicle worked perfectly until yesterday. My wife locked her keys in the vehicle while it was running. After we unlocked it with secon set we brought it home and parked it. An hour...


You should try resetting the computer. This is done by pulling off the negative cable to the battery. Pull it off for 20 seconds, on for 10 then back off for 20 then back on permanately. You may have tripped the anti theft system on your vehicle. This may or may not solve your problem, but will eleminate some things. Good luck to you. Thanks for using fixya!

Sincerely,

JC
