hello group. i have a 96 lt1 vette. thought my key fob had gone bad so i bought another one. when i walk away from the car nothing the doors dont lock and when i walk up to the car they dont unlock. although when i push either button doorunlock/are hatch thoose functions work fine. this does this on both remotes. any ideas why the automatice feature wont work??????????????????/

 

It might be disabled. Try holding down the door button on the fob for 10 seconds. You should hear the actuators lock and unlock quickly. Then see if it works.

 

If the system is turned "off" it will act just as you describe. Try as Ttime suggests. Stand close to the drives door and hold the lock button in long enough for you to hear the locks cycle. If the system was off, it will now be on and vice versa.

 

thanks for the input guys. tried holding the door button down the locks "cycled" after about 2 sec. one time i did it they locked in the end next they were unlocked. never did the automatic lock start working when i walked away though. i guess i can manually lock and unlock them now though so thats good. any other ideas what might get the "automatic" part to start working???????

 

In order to get mine to work I had to let it cycle a few times and I believe you have to keep the drivers door open.

 

When holding down the door button, make sure you're close to the car, then after about 2 seconds the door locks will twitch, but after 5 or 7 seconds the locks will cycle fully. That full cycle changes the state from 'auto' to 'off'.
So try holding down the button longer, until the locks cycle fully. My '95will switch from 'auto' to 'off' with the doors open or closed.
Hope this helps.

 

Sorry for the omission.
Holding the button down until the locks cycle fully will either turn the system off (if already on) or on (if already off).
Don't do it twice or you're back where you started.

 

To turn the system off:

1. take the ignition key out of the ignition.

2. press "door" on the transmitter until the door locks cycle(about two seconds)

to turn the system back on, just repeat the steps.

To check that the system is off, turn on the ignition, The "passive keyless entry" light on the DIC should not come on. If light does come on for a second or two, then the PKE system is still on.

You can alson check whether the system is on or off bt closing the door and walking away with the keys and transmitter. If the doors lock the system is on.

This is out of my '94 Manual.

Hope this helps..

 

thanks for all the replys. unfortunately i tried them and still cant get it to work. when i hold the door button down after about 2 sec the locks will whatappears to be "cycling" funny thing is first time i do it the locks will be in the lock position when it stops and next time it will be in the unlock. not sure what that means but thats what it does. i held the button down for 20 sec and after the lil cycle it does after 2 sec nothing happens. after each time i did the cycling i put the key in and turned it on and the Passive keyless entry light on the dic comes on like it always has at no time has it ever not lit??????? i am open to anymore ideas???????????????????

 

My PKE goes non functional if my cell phone is in the car and charging thru the cigarette lighter.
Is there any chance that your cell phone is charging in the car???
If my cell phone is anywhere nearby (not charging) my PKE range is reduced to about 1' so I have to get very close to the driver's door before the PKE will unlock the car.
If my cell phone is nowhere near, the PKE works fine.

Also, are you aware that the PKE can be in either of two modes; open the diver's door only or open both doors? And the range is much better near the driver's door or the rear end, regardless of whether one or two door mode is selected?

 

Since you bought a new FOB, did you go through the steps to match it to your car?

From my 1996 Owners Manual:

Matching Transmitter(s) To Your Vehicle
Each key chain transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter
is lost or stolen, a replacement can be purchased through
your dealer. Remember to bring any remaining
transmitters with you when you go to your dealer. When
the dealer matches the replacement transmitter to your
vehicle, any remaining transmitters must also be
matched. Once the new transmitter is coded, the lost
transmitter will not unlock your vehicle. Each vehicle
can have only three transmitters matched to it.

To match transmitters to your vehicle:
1. Move all transmitters out of range.
2. Turn the ignition key on.
3. Push TRIP OD0 on the Driver Information Center twice.
4. Within five seconds, press and hold FUEL INFO
until the PASSIVE KEYLESS ENTRY light comes on.
5. Turn the ignition off, but leave the key in the ignition.
The PASSIVE KEYLESS ENTRY light should begin to flash to show
the system is in programming mode.
6. Bring one transmitter into range. The light will stop flashing and
stay on to show that the code is stored.
7. Move the transmitter out of range. The light should start
flashing again.
8. Repeat Steps 6 and 7 with each additional transmitter.

The programming mode will shut off if:

You don’t program any transmitters for two minutes.
You take the key out of the ignition or turn the ignition on.
You have programmed three transmitters.

 

thanks guys, yes i did program the new key fob and it does the same as the old one. buttons work fine just no automatic locks when you walk away. my cellphone was not near the car when i was doing the checking? i have heard how one are both doors can unlock but never done that. both are working right now when i hit the button. any more ideas????????????????????????????????

 

There are a couple of fuses, I'm assuming the 96 is the same as 95. Check fuse no.26-PKE module & fuse no. 40. #40 also has the radio control head & radio receiver on it, so if the radio is ok you can eliminate that one. Also make sure the driver & pass side door locks are in the verticle position?

 

have checked all fuses in the panel by the pass door and the ones under the hood. also radio works.
