How To Reset Pass-lock Security On 98 Chevy Silverado Or Bypass It?
I put a new stearing collom in my 98 silverado and now the security light flashes it will start and die
It depends on the key on what you can do. If you have one of the newer style keys without the chip on the side then you can try to cut the key on and leave it for 15min. After you let it sit for 15 min then cut the key off and back on for another 15 min. Then try to crank. I know that works for some gm's but I have had some where it didn't work right on. If you have one of the keys with the chip on the side they the only way is to bypass it. You would have the measure the resistance of the chip. If the car doesn't see the right amount of resistance then it will not let the fuel injectors work. After you find out what the resistance is then you would have the cut the two small white wires on the bottom of the steering column and solder in resistors to get the same amount of resistance. You can get resistors at a lot of electronic stores.
Lock the truck from the inside or by remote, take your key and unlock the passenger door first! Then take your key and unlock driver door , place the key in ignition and turn to run position . Now if your lucky the security light will turn off and turn the truck on.
