Have a 1998 chevy surburban replaced steering colum now truck will not start i have the new key that came with the new colum still does not start

Lost Key To Chevy Cobalt would like to know how to re

as the immobilizer system is around the switch , by replacing the column , you have fitted a different immobilizer so the key will not deactivate the immobilizer

if they tried to pull the wheel lock located in the steering colum. they may have damaged the key sensor that read you security codes off the key. which means you`ll need to replace the key sensor in the colum. Unless they pulled a wire off under the steering colum. look down the steering colum and up underneath and see if there are any plugs out. PS some cars are designed of extra accessories which case you may find a few plugs away from the colum that aren`t connected to any thing these won`t be the issue but.

remove the steering colum covers were the cyn is look at about 3 o clock theres a small hole turn key to on insert a pick into the hole and push while turning the key and pull out.

Its probably something in the harness going up the steering column to the key switch.

its located at the base of the steering colume by the firewall on top of the colume.there is a rod that comes from the top of the steering colume down to the switch.when you turn the key it moves the rod which moves the switch internally allowing the car to start.

I would check your brake light swich located under dash just fallow your brake pedle with a test light see if you have power going to it slitely press brake pedle see if other side of switch has power (key on car not running) if not try ajusting it by pulling on it or unscewing it if all checks out ok replace turn signal switch disconnect battery remove center part of steerring remove center bolt with steerring puller pull steering wheel with locking plate puller pull locking plate remove turn signal handle emergency button three scews holding turn signal under dash fallow steering colum disconect wires on right side (passenger side) tape a long wire to end of connector pull turn signal without pulling tape wire all the way out so you can tape it to new turn signal wire connector to be able to pull wires back down steerring colume (you might have to losen steerring colume and bracket two scews under dash four on steering colume)

If the key is acting proper and lights are working good then there is a problem with the start system.need more info for proper fix.do you here click noise in start position? does lghts dim when key in start position?

If you are using the key and switch that was in replacement column, the resistance of the key pellet for your car is wrong. Provided you connected everything up then the easiest way would be to take your old key (out of old part) and the key from your replacement column to a Cadillac dealer. They can read the resistance of your old key and cut you a new key with the proper resistor. That should start your car.

If I remember you have to remove the steering wheel to get to the release for the key switch to come out.If you have a tilt wheel let someone with experience do it,you will be glad you did,and it wont be cheap.Sorry!
