keyless entry

[1993blazerlt]

how do you program these remotes? I just got one for my 93 blazer and have no idea how to program the remote

[Blazer69]

i know on my 96 u have to short out 2 of the sockets on the comp plus under the dash...like #'s 2 and 7 or sumthing....not sure if the 93 is anything close but...

[1993blazerlt]

i don't think it is the same the big difference being i have OBd 1 andyou have OBD 2

1.Get a piece of jumper wire.Leave ignition switch off.

2. Connect ALDL terminal A (upper right) with Terminal G (lower left). Door locks will lock and unlock in approximately 2 seconds.

3. Press "UNLOCK" button on remote. Door locks will lock and
unlock in approximately 2 seconds. The remote has now been programmed.

4. Disconnect the jumper wire from the ALDL.

5.Close your back window.

it did not work i waited a while tryed it the car on, off and in the run postion it never made my door locks work

[BadV6Blazer]

Well that's the procedure for programming the remote. :rolleyes:

[Blazer69]

thats how i reprogrammed mine several times....

[1993blazerlt]

i think it is different for the newer blazers mine is a 93

Mine's a 92.You have some sort of problem with yours,or the info I posted would work.

[1993blazerlt]

what sort of problem could it be. My power locks work fine on there own what could casue them not to work using this method?

[XxInFaxX]

OE? Operator Error :)

what sort of problem could it be. My power locks work fine on there own what could casue them not to work using this method?Well it could be your jumper isn't making contact,or the remote module is fubared/missing.

where besides gm would i be able to get a new remote module. I tested every thing and that led me to belive that it is the module that is causing the problem

[1993blazerlt]

I have keyless entry in my blazer from the factory. I have a new remote but i can not get it to program. I have gone through most of the trouble shooting and have not been able to get it to work. This is really making me made i want to get this working.

Ground pin G of the Data Link Connector (DLC).
Press any button of the first transmitter to be programmed.
The receiver module will respond by locking/unlocking doors and activating rear window release.
Press any button of the second transmitter to be programmed (if used).
The receiver module will respond by locking/unlocking doors and activating the rear window release.
Remove the ground applied to pin G of the Data Link Connector (DLC).
Transmitter operation is verified by locking and unlocking the doors and activating the rear window release.

I have tryed to program it that way and nothing happens.

[Sparky2263]

You've got mail ;).

Sparky, would you have the programming instructions for a '99 Grand Am? My son just bought a GT but it didn't come with the key fobs. We bought a couple but need programming instructions to save a trip to the dealer.

Thanks.

A remote door lock receiver may have up to 4 different transmitters programmed. You may program a transmitter to more than 1 vehicle providing the remote keyless entry systems are similar. When reprogramming 1 transmitter, reprogram any and all other transmitters (maximum of 4 total per receiver) at the same time in order for the other transmitters to work.

IMPORTANT: Leave a window down in the vehicle while reprogramming the remote control door lock receiver system. This procedure will avoid an unintentional lock out if the reprogramming is not performed properly.



Turn off the ignition.
Utilize a Tech 2 to program the remote door lock receiver.
Enter diagnostics (F0).
Enter body (F1); select the year (X) and body style (N).
Select "Remote Function Actuation" (F3).
Select "Special Functions" (F2).
Select "Program Transmitters" (F0).
Select the number of transmitters to program (1-4)
Follow the on-screen instructions; press continue, wait for the locks to cycle, hold the lock and unlock buttons simultaneously for 15-30 seconds , the locks will cycle again.
Exit the vehicle. Attempt to lock/unlock the doors to verify the programming.
Perform the following steps if the above procedure does not program the transmitter.
11.1.Reconnect the Tech 2.11.2.Enter service programming (F1).11.3.Press the "REQUEST INFO" key.11.4.Select "Reprogram Existing Module"11.5.Exit the vehicle and remove the Tech 2.11.6.Follow the existing procedure to reflash the body control module.


Well, just damn. Gotta have a Tech-2. Here's the resynchro procedure;

Resynchronization
Resynchronization may be necessary due to the security method used by the remote function actuation system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that the receiver has sent previously. This prevents recording and playing back the signal from the transmitter.

Resynchronization does not send the mathematical formula to the receiver. Resynchronization verifies the programmed mathematical formula that is in the transmitter. Resynchronization is successful only if the transmitter is already programmed. Resynchronization may be necessary under the following conditions:


The transmitter is weak.
The transmitter battery was changed.
The vehicle battery is very weak.
The vehicle battery was changed.
The vehicle battery was disconnected.
The transmitter is pressed more than 255 times outside of the range of the receiver.
Complete the following steps in order to resynchronize the transmitter with the receiver:


Press the LOCK and the UNLOCK buttons on the transmitter simultaneously for 7 seconds .
The receiver will acknowledge resynchronization in the following manner:



If all of the doors are locked, the receiver will unlock and lock all of the doors except the driver door.
If all of the doors are unlocked, the receiver will lock all of the doors.

Thanks, Sparky. That's sort of a big help. Now I know the procedure, but I now know I also need a Tech-2 programmer. Maybe I should take it to the dealer.... on the other hand, what's a Tech-2 programmer? I didn't find anything on the web during a quick search.

[Sparky2263]

Tech-2 is the scanner/programmer all the GM dealers have.

Kinda' pricey also.......

[20Xtreme02]

Yeah, no shiznit!!

[20Xtreme02]

Sparky, will the programming instructions you posted for the '93 also work on my 2002 Blazer? If not, do you have those? They would be a good thing to have "just in case".

Thanks.
