Question regarding remote locks
Hi!
I'm the proud owner of an used dark gray 2004 Trailblazer LS. I received the truck from the dealerwith only the regular key--no fob. I was wondering if 1) I could buy one off eBay and program it, and 2) Did all Trailblazers come with remote door locks?
Thanks!

RE: Question regarding remote locks
First thing to try is to ask the dealer if he has a box of key fobs where you might find a working fob for your vehicle. Used car dealers that have been in business for a while will have such a box, and may let you find what you need. This site which sells fobs has pictures of the fobs so you will know what you are looking for.http://www.keynfob.com/
If you can't find one from the dealer, then yes, you can buy one on the internet or from eBay.
You should be able to confirm that you have the keyless entry system and that it is working by trying to put it into programming mode. Here's how to do that:
Transmitter Programming
Important
All transmitters which are to be recognized by the Liftgate Module (LGM) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
You may program up to 4 transmitters, using either of the 2 following procedures:
Method 1 - No Tools Required
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation.
(scantool needed for method 2)
