trans sport keyless entry

hello i have a 1995 pontiac trans sport i love the van except 2 issues i cant find the programming instructions for the keyless entry and the overhead temp shows minus 40 everytime i start the van the highest it has read is minus 18 how can i take care of these 2 problems any help would be greatly appreciated thanks

To program the keyless entry, you will need to remove the glove box... Look above the area of the light, and you will see a black box this will be the keyless entry module... On this module you should find a button, you will press and hold that button to program the remotes..

I think if needed I can dig up the instructions to program the system...


For the temp reading you may have a bad Temp sensor... It resides ahead of the radiator attached to the header panel...

To expand a little bit what JRS said:
- Ignition "on"
- press the button until the power locks cycle once. Release button

[From this point on, repeat for each remote]
- press and release the button once again
- you have 10 seconds to press any button on the 1st remote you want to program
- once you press the button, the module will indicate the remote was accepted by cycling the locks again.
