Somehow - we have managed to loose the keys to our K5 Blazer. It's just a spare truck - and used mostly for trail use, but we can't start it now - only had one key (well actually we had about 6 different keys - every door, ignition, etc. took something different from all the repairs over the years).

Any ideas about what to do about it?

you can either get a new lock cylinder (new key included), or just hotwire that shit... :D

It's really not that hard to change the key switch on GM trucks. I can do the one on my s10 in about 30 mins start to finish with the right tools.

What he said...

but maybe 10 mins if you're good :p

well you can always run a pushbutton switch for your started thats what i do.

in order to do that though, the ignition still has to be turned to the on position.

Thanks for the replys... I was going to hotwire it, but we still need the key in order to make the truck street friendly. I think that I will replace the lock switch - could someone that has already done that walk me through the steps? I am not sure how to go about replacing the lock without having a key. I'll also have to replace the door locks - as they are all missing, but I know how to do the doors.

Thanks.
