I locked my keys in my 2005 trailblazer how do i unlock the door?

you have to have a special tool that will reach over the top of your door window and then down to hit either the window control or door locks can buy these at any auto parts store but any wrecker driver has these tools and can get in in less than 5 mins... a "slim jim" will not work unless it is manual door locks (as opposed to electric)

new cntroller/switch set for the driver door. The switches may have broken inside their housing. easy replacemnt as it usually just pops out the hole its in. Just pry gently with a rocking motion.

its prob a relay or main fuse gone which should be located under the bonnet in the electrical box near the ecu if not try the inside fuses or it could be an emobiliser problem the best thing to do after checking all those is to bring it to a garage and ask them to put it on the diagnostics believe me its the best and cheapest way out of it youl know exactly whats wrong with the car and how much it will cost to get it fixed for the sake of around 80 euro. hopes this helps
