Security light & other red lights come on & restricts speed to 5 mph

The problem may be your Vats security system. This causes the car to either "not start" or "shut down" while running. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start.
Cheap fix:
----- Bypassing the key
Never worry again fix:
----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites. Read up, this is a common problem, but it is costly to fix. That NEWROCKIES guy can help you with anything. just send him a message

Trunk lock will not open keydoes not turn used pb blaster

I had this problem in my 1998 olds 88ls pretty much the same car. Open the glove box there should be a little switch in there that say trunk lock/unlock. make sure its switch to the unlock side. the idea for the switch is so you can put valuables in the trunk flip that switch to lock then lock the glove box and people cant get your trunk open and steel your stuf.

1998 buick century security light stays on but vehicle starts & runs fine?

The security system (VATS/PassKey) is having problems, it's typical on those cars and it gets worse till the car won't start anymore. You can find a great write-up here: , it was the only thing that saved my Park Avenue.

1998 S-10 tuck runs good,then few days later when the truck is turned off wont start,cranks good,changed fuel pump and filter,its getting fuel and spark theres a security light comes on,then sits for few...

Hey have you recently changed your head unit. I have a 2000 s10 2.2 and i recently hardwired my pioneer 4000ub head unit and the security light came on upon not starting. every time you try to start the car while the security light is on it will add 10 minutes onto your time. For the security light not to come on you need to check your wiring. just remember dont keep trying becuase it wont work!!! find the problem and fix it.
