Pass key system or security

Electrical problem
1999 Chevy Suburban V8 Four Wheel Drive Automatic 135000 miles

Is there any way to reset the passlock system. Mine keeps triping and stranding my wife. Can I bypass it completely?

Hi, I am trying to program a new key fob but I cannot get the vehicle in the learn mode. This is a K1500 old body style. I have tried holding the door unlock button down and cycling the key method and it does not work. I have also read to short pin 4 and 8 together on the data port to enter "learn Mode". I would like to confirm this is a safe method before trying it. Anyone know? I have also checked the fuse and it is fine.

This method worked flawlessly. Thank you so much.

1999 Chevy Suburban LT 5.7 auto 4x4 151,000 miles, I BELIEVE the factory installed alarm system. It's the one with the remotes that have Lock, Unlock, and Rear 2x buttons.

I just bought this truck on Saturday, and the keyless entry didn't work. First thing I checked were the batteries in the remotes. They were both leaking, so I replaced them right away. Tried the remotes, still nothing. I have a LITTLE experience with alarms, so next thing I do is start playing with the valet switch. Beautiful, keyless entry and alarm seem to be working fine, except no chirp or any kind of door lock confirmation sound.

Today I accidentally hit the door lock button inside the truck twice in a row (the one on the door, not on the remote), and the alarm started going off, just as it did if I hit the lock button on the remote twice. I couldn't get the alarm to shut off with the remotes. I put the key in and it started right up, but the alarm was still going off. People were starting to get annoyed, so I started playing with the valet switch again until it finally shut off.

Don't ask me what I hit in what order, cuz I couldn't remember to save my life. But now the remotes don't do anything at all. I spent a few hours fooling with it, and looking up any info I could find online, but no help. Does anyone have programming instructions for this alarm? I know the dealership I bough the truck from wouldn't have a clue, and I really don't feel like paying a real Chevy dealer to look at it. It's a real simple thing to fix if I just had the instructions.

Someone PLEASE help me get my alarm working properly.

Oh, on another note, is it me, or is the range on the remotes REALLY small? When they WERE working they usually didn't work more than 15 or 20 feet away.

And 1 last question. What is the 4th contact pad in the remote for? It only has 3 buttons, but there in a contact for a 4th, and the case has an indentation or whatever on the inside where a 4th button would go.

Thanks in advance for all your help. I look forward to reading all your replies.

I don't know who installed the alarm, but it seems to be the exact same one everyone else has that asks questions online about an alarm in that truck. I don't have the owners manual, or else I would have already checked it. It didn't come with the truck.

There is a special sequence that you go through to program the remotes. I found it a couple weeks ago while doing a search online and used it to reprogram my remote. Do a yahoo search and you should be able to locate it. Basically if I remember right, you turn the key on then off on then off then on and leave it on. Hold the lock button down on your console, the doors will lock and unlock, then hold the buttons on the remote locked for about 15 seconds or until the doors lock/unlock. And thats it. But search the net, you'll find it like I did. Good luck!

My daughter locked the door I opened it and it engaged. I do not have a remote to the truck and I do not know how to get the truck to start so I can take my babies home.

I searched and found the sequence.I hope it helps:

1) Close all the vehicle doors.
2) Insert the ignition key into the ignition lock cylinder.
3) Press and hold the door unlock switch.
4) While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
5) Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
6) 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.
7) Repeat the previous step to program up to four transmitters.
8) Turn the igntion switch to the RUN position in order to exit the keyless entry transmitter mode.
9) Operate the transmitter functions in order to verify correct system operation.
