How do i remove an ignition in a gmc jimmy 2000 without a key?

Hello, Dan. First, disconnect the negative (-)/ground on the battery Dan are you mechanically inclined. If not then don't attempted this job.

You will need to remove all the plastic covers on the steering column. Remove the horn ring.--two screws under the steering wheel. Remove the horn ring and disconnect the horn plug. Remove the steering wheel nut. Use a steering wheel puller to remove the steering wheel.

Remove the turn signal switch that fit around the upper part of the steering column. Then remove the some of the parts that are associated with the steering wheel and/or column.

Now, look at the ignition switch flange, it a big chunk of aluminum. Now look for a large aluminum dowel pin 5/8" in diameter that is driven into the chuck of aluminum but it is parallel to the steering column.

This aluminum dowel pin will have to be drill out before you can get ignition housing off, If there is adjustable steering column lever, remove this also.

Now, once the dowel pin has been removed, looking for a **** in the ignition housing. Take chisel and insert into this ****, drive the chisel into the **** until the ignition housing is loose to be remove by sliding it up over the steering column.

If you buy a new ignition switch, on purchase the switch with keys. Don't buy the hole new ignition housing.. If you do it will get expensive.

In the ignition (old) housing drive out the ignition switch pins that keeps the ignition switch in the housing. Install the new ignition switch re-insert the ignition switch hold pins.

I am fairly sure that Carquest/ NAPA some other larger auto parts will have ignition housing bolt. If they try to sell you a replacement aluminum dowel pin don't buy it. It is almost impossible to install the aluminum dowel pin without the proper tools, so use a bolt to squeeze ignition housing together.

Before putting everything back together. Now, check the new ignition switch to make sure it works. I wish you lot of luck. GB...stewbison
