• The Manufacturer decided to not produce this vehicle with self-programming capabilities.
• You must get an Automotive Locksmith to program the remote to your vehicle for you.
• If your vehicle requires professional programming we tell you, so you're not left with any doubt and searching all over the internet.
• It's still much cheaper to purchase a remote from NorthCoast Keyless and get it programmed by a Locksmith rather than buying from a Dealership!

Cheapest alternative to purchase a "new" remote key fob is on eBay. Search for "remote key fob, 2004 Trailblazer". Check and/or inquire about programing instructions.

You need to get an aftermarket coded key which can be cut by the serial number of the vehicle.
You need to be a locksmith to get the cut codes or know a locksmith.
Then you have to get the car to the dealer and have the key programmed using the Tech 2 scanner.

You can take the car to the dealer and have them give you a key, programmed and everything but it will cost around $300 for the 1st key.

I bought a 2001 Catera for $1,500.00 because it had no keys.

I used serial number to get key codes and cut the key; doors opened and seller retrieved her personal stuff.
I towed car to dealership and had the key programmed; $130 for 10 minutes work (min 1 hour shop charge).
I then programmed 3 more keys (using a key code reader) instead of letting the dealership rape me.

BTW, they (dealer) also want $350 for a programmed door remote; the stock remote!
Instead, I bought a remote starter unit (Bulldog) with 2 remote fobs for $100 and now my wife can start and find her car easily.

first you should double check to make sure the batteries are installed correctly ,then get the new car manual out of the glove box ,and check for the reprogram procedure for your remote . every car manufacture has there own procedure , example,I have 03 mustang mach 1 the procedure goes something like this.turn key to on position..put drivers side window up then down open and close driver door then turn lights on and off then radio on off and so on

in the 1996 sunfire GM uses an anti theft lock system. It can be triggered by all sorts of things. In order to relinquish this you must have a key to turn the ignition. These are not coded just plain cut keys. Once you attain this you put the key in and turn the ignition to the ACC position and wait ten minutes (theft lock light will turn off), turn off and take key out. You MUST do this 3 times and then the theft lock will be disarmed.

try reprograming the remote, if that doesn't work u may need a new remote these are the factory instructions.
1. Switch ignition on with a key (don’t start the engine!); leave key in the ignition.
2. Mechanically lock vehicle at left front door, using second key.
3. On remote unit, press "Open" button once. A short horn signal will sound.
he "Open" button is pressed once for programming the first, or a single,
remote unit.
�� When programming additional remote units for the second, third or fourth
memory addresses, press the "Open" button two, three or four times, in
one-second intervals.
�� Example: press the "Open" button once, wait 1 second, then press once
again to program the second remote unit.
�� After 6 seconds, press "Open" button once to activate the coding ocess.

4. The remote unit will now be coded, and it can be used to unlock the central
locking system. Switch ignition off.

The key must be removed from the ignition before the remote unit can be used to lock
the vehicle.The coding process can be repeated up to 4 times for additional remote units.
In between each remote unit coding, the ignition must be switched off.
