THERE IS A CHIP IN THE KEY I BELIEVE. THERE IS A RELEARN PROCEDURE YOU CAN TRY IF WHEN YOU TRY AND START IT THE SECURITY LIGHT FLASHES. HOOK UP A BATTERY CHARGER. TURN THE KEY ON AND TRY AND START THE CAR AND RELEASE . DO NOT TURN KEY OFF LEAVE IT IN THE RUN POSITION. AFTER 10 MINS THE LIGHT WILL STOP FLASHING. TURN KEY OFF. TRY AND RESTART CAR AND AGAIN DO NOT TURN KEY OFF LEAVE IN THE RUN POSITION. LET SET 10 MINS AGAIN. LIGHT WILL STOP FLASHING AFTER THAT 10 MINS. DO IT AGAIN FOR THE 3RD TIME. SHUT KEY OFF LET SET 5 SECONDS AND START THE VEHICLE. HOPE THIS HELPS
there is more to it than just using both keys there is a special way to do it put old key in turn on off 3 times then remove old key and put in other one and turn key on ,that should get it , is anti theft light flashing?
turn the key on and wait till the security light stopsflashing ( this could take as long as 30 minuets ) then turn the key off then back on but do not try to start the engine and wait till the security light stops flashing ( again this could take as long as 30 minuets ) then turn key off then turn key on and start engine.
"If you have the airbag light, it will show steady for a few seconds (the manual says 7 secs) after you turn the key from off to on (but not start) and then start to flash. Here is how to reset it:
1. Turn the key from off to on.
2. Watch the airbag light closely. It will stay on for a few secs. and then as soon as it blinks off (the start of the flashing), turn the key off instantly.
4. Repeat steps 1-3 two more times until you have done the cycle three times.
5. Now turn the key on and watch the light. It will start blinking in a different, slower manner. This is diagnostic mode. You can watch this for a little while, no hurry.
6. Now turn the key off again, Count to 5 like in step 3 again, and turn back on. If the procedure worked, the airbag light will not be flashing.
If it does not work the first time, just repeat the steps again."
Take it to a different shop. Something is wrong with it. However, when the airbag light is on, that means the airbag will not deploy in an accident. You should have that fixed first. The dealership is the best option for making the keyless entry work. If this was at all helpful, please rate. Thanks for
asking.
The way to approach this sreies of issues is to first remove the remote start/alarm from the equation and restore the vans electrical system back to original. From there, if it persists, we can do more trouble shooting. Let me know and I can walk you through the process. This is definately a problem that does require a diagnostician. Thank you for the level of detail you provided!
it is a problem with the anti theft system
to reset it to the key
you put the key in turn the car on do not start the car
the securty light will flash wait untial it stays on (it takes about 1 min.) turn the key back to off you have to do this 3 times. you only have 10 sec. to turn the key to off after the light stops flashing. This will program the passkey 3 system to the key you are trying to use
