have a question about keyless entry..

I bought my 1997 Blazer last week used from a dealer. What I need to know, is if it has keyless entry or not. It didn't come with the keyless entry remote, but it has a little LED light near the light switch, and I don't know what that is. Does anyone know how to find out if I have keyless entry?

here is the picture of the little LED light.

I know this question is kind of :screwy: but, If it does have the capacity for keyless entry, then I could go buy a remote.

Since I didn't get an answer quick enough, I called the local GM dealer, and he told me my car was equipped, with keyless entry. All I need is the remote. Does anyone here know the programming instructions for a 1997 Chevrolet S-10 Blazer? if so, please post it on this thread! :naughty: :icon16:

That LED loks to be from an alarm system or an aftermarket remote start.

Have someone check it out because I have the exact LED in my truack and guess what, I installed a remote starting system.

Also, I see your temp gauge there, is that the hotest your engine gets or was it just warming up?

I'll get it checked out.

Actually, that's the hottest the temperture gauge gets. I had driven it the night before, and parked it, when I woke up this morning, I took those pictures, and hadn't turned the key to look at the actual temperature. but that's the hottest it gets.

So if you have been driving for over 30 minutes that is how high the gauge gets?

That's the hottest. No kidding.

Welp, it is a great thing that you posted that picture because you know what, we have found a problem that probably has been killing your fuel economy lately.

Your thermostat is stuck open and not allowing the engine to come up to temperature.

I would recommend:

New T-stat.
Flush and fill with new Dexcool
New Rad Cap <---very important.

Yep, you gotta get that fixed. If not, it will lead to more problems than just poor gas mileage. These new cars love to be at least 200 degrees.

2nd note, guarentee you have or had an aftermarket alarm in your truck. That LED light is not from GM. Take a look under the dash and look for wires that aren't in the OEM wirelooms and such.

For your programming problem, take a look at the Nonspecific forum. There are three threads on keyless entry. The one started by rubberman looks promising.

Remotes on Ebay by the hundreds, not a lot of money either.

Jesus, you guys are life savers! I was actually thinking it was a little low on the temperature, considering it's got 162,000 miles on it. But honestly, it doesn't get any hotter, and I get great gas mileage. It's got I think a 15 or 16 gallon tank, and I get 300-310 miles to the tank. That doesn't seem that bad, I used to have 1997 cavalier, and it's got the same gas tank, and the gas mileage on that was 425 per tank.

Yip, swap out that Tstat ASAP and you will be AOK.

Have you ever mixed the orange dexcool with the green stuff?

I did on my cavalier. Works like a charm. No problems that I ever knew of.

I have a 97 service manual, three huge books. If you get a remote repost and I'll try to find the info. Hard to find anything in those manuals.

Very nice of you to offer tom3.

hey diddy, what did they have to know to tell ya about the remote.

All you have to do, is tell them the VIN number, and they can check to see if it was factory equipped with the keyless entry. If it does, then you can buy the remote from them, and they usually program it for free, since you bought the remote from them.

here ya go......


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, the old transmitters will be deactivated.


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.

Great post cobra1, does this apply to all years?

I tried that method, and nothing works. I turn the key on then off, then on then off, while holding the unlock button, and nothing works. a little help?

Might first try a resynro. process. Stand close to vehicle and press and hold unlock and lock buttons for seven seconds. Door locks should cycle. If not you need to reprogram. Procedure from service manual for a 97: Book 1 section 9K4

Use a jumper wire to provide a path from the RKE programming circuit (pin 8) to ground (pin 4) on the data link connector (DLC). The remote control door lock receiver will respond by locking, then unlocking all of the doors and unlatching the rear window to indicate that the receiver is in the programming mode.
With the circuit remaining grounded, press any button on the first transmitter to be reprogrammed. This will store the access code for the transmitter and the receiver will respond by locking, then unlocking all the doors etc.
Press any button on the second transmitter if used.
Remove the jumper.
Test the transmitters.

The DLC is under the dash on left side of steering column. Pin 4 is a ground with black wire from back side. Pin 8 is the RKE circuit with black wire/white stripe.

This is from the factory manual but for sure, use at own risk.

is the DLC the port where you connect the ODBII Scanner? :dunno:

Yep, that's it. It's numbered but hard to see the numbers, really small and on the rear near the wires.
