How to program the keyless entry remote ---for mk3 VW
back to 1000q: mk3 "how to" index and FAQ
For VW cars 1998 and newer, see 1000q: mk4 key FAQ or 1000q: mk5 key FAQ and 1000q: immobilizer FAQ.
Introduction
This article shows how to check if you have keyless entry and how to program the keyless entry remote for 1996, 1997 Passat TDI or 1996, 1997, 1998, 1999 Jetta TDI.
Unlike mk4 cars that used an immobilizer, you can buy and program keyless entry remotes from any source and have the key cut anywhere. Mk3 cars did not use an immobilizer.
Checking the part numbers
Aside from the VW part number, your remote should have an FCC number that ends in "T" for transmitter. This number should be identical to the keyless entry module's FCC number except it should end in "R" for receiver.
If you confirm that you have keyless entry, you need a remote. If the white box is on a 1998 or 1999 Jetta and is VW part#1 hm 937 045m or # 1hm 937 045q - white rectangular box w/2 plugs with FCC id# m3ghu01r , you need a remote with the FCC id# m3ghu01wt (says clarion on the back)
If your white box is from a 1995-1997 Jetta, the white box VW # is 357 953 233B and the remote is VW part# 1em 937 047a, with FCC id# GOH-MM6-101890
Parts
I recommend http://www.fixmyvw.com 's key cutting service. They sell new remotes and can even cut you a key from a clear photo of your key. They can cut your key with the VIN number but it's more expensive than doing it from a photo. They also rent the key programming tools and sell parts such as new circuit boards, covers, vw emblems, and immobilizer chips.

If you don't know if you have keyless entry
First check to see if you have a keyless entry module. If so, you just need a remote. Slide some feelers or spark plug gappers around the headlight switch. Remove the headlight switch. If you see the white box, pictured below disassembled, you may have keyless entry. Double check with the below procedure:

If you see this silver box, you do not have keyless entry. You can add it if you have this alarm module, see 1000q: keyless entry retrofit for the full procedure.
