2003 Chevy Trailblazer keyless entry?

[shane w]

The dealer I went to said it didn't have it.Can I do something to activate it or do I have to buy another module to put in it.I know there is all kinds of tricks to reprogram things on these Trailblazers. Thanks

You used to be able to buy the module for the keyless entry but the last time I checked GM had quit doing that. If you look in your glove box there is a white sticker with a bunch of 3 digit codes look for AU0 if it does not have that it cant have factory keyless entry. You can still get an aftermarket module. I am sorry but there is not trick to reprogram the trailblazer.
