I bought a keyless remote for my 99 blazer of off ebay for a spare. All the numbers match the one I have. I need to reprogram the new one. I tried the on/off method but it didn't work. Thanks for any help

Welcome to AF. Here is the procedure to program the remotes.

Transmitter Programming

Important
Different keyless entry systems are used on General Motors vehicles. The parts are not interchangeable even though the parts may appear to be similar. Observe the back of the transmitter in order to properly identify the system. On 1999 S/T pickups and utilities, use a transmitter identified with GM/UTA preceding the part number.


With the driver door closed, hold down the power unlock button on the door panel.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Release the power unlock button on the door panel. The remote control door lock receiver will respond in the following manner in order to indicate that the receiver is in the programming mode:
Locking the doors
Unlocking the doors

Important
All extra transmitters must be programmed at this time. When a new transmitter is programmed, it will deactivate the old transmitters.


Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:
Locking the doors.
Unlocking the doors.
Repeat step 7 for each additional transmitter.
Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
In order to reprogram the remote control door lock transmitter with a scan tool, refer to Scan Tool instructions.
Memory Seat Recall Programming
Adjust the driver seat to the desired position.
Press the switch labeled SET. A chime confirmation will be heard.
Press the desired position switch labeled 1 or 2. Within 5 seconds from pressing the SET switch, a chime confirmation will be heard.
Press the UNLOCK button on the desired transmitter (key fob) within 5 seconds from pressing the SET switch. A chime confirmation will be heard.
The transmitter (key fob) is now programmed with the desired position switch. Pressing the transmitter UNLOCK button will cause a recall request to be initiated and the seat will adjust to position 1 or 2.
The stored memory positions may be changed without having to reprogram the transmitter.
The transmitter feature is available in all ignition positions.
Memory Seat Recall Unprogramming
Press the switch labeled SET. A chime confirmation will be heard.
Press the UNLOCK button on the transmitter (key fob) within 5 seconds from pressing the SET switch.
Do not press any memory switch or power adjustment for 5 seconds. Pressing a switch will cancel the unprogramming event and the transmitter will remain programmed.
The transmitter (key fob) is now unprogrammed and pressing the UNLOCK button will not effect memory seat operation.
No chime confirmation will be heard when the UNLOCK button is pressed if the transmitter is unprogrammed.
