Just bought a remote from the wrecker for 1993 Bonneville SSEi. Does anyone
know how to re-program this used remote unit to open my car. I already have
one remote that is working right now, but there are two drivers in the house
so this remote is going from one hand to another. I am concern that we may
lose this remote some days so just want a spare one.
Please note that the vehicle is equip with pass II security system.
If I remember correctly, this would be the older system used on cars
prior to OBDII and may be programmed manually without the need of the
scantool. The Bonneville is an H-body and I am quite familiar with
programming the W-body but I would expect them to be similar.
The W-body has a "Programming Pigtail" connector hidden under the rain
gutter of the trunk on the right side, close to the antenna. All you
need to do is use a jumper wire to ground this pigtail connector and
you will "hear" all the locks cycle once to let you know that you have
entered the programming mode. Then you need only press one button on
each remote and wait until the locks cycle for each remote entered to
acknowledge the codes acceptance. Note that the reciever can only
hold 4 remote codes and programming the 5th remote erases the first
code. Also, as soon as you enter the "programming mode", you erase
all previous programming.
Now with your Bonneville, I can't remember for sure where the
programming jumper is but it may be under the right side of the dash.
I do remember that on some models such as the N-body, that it was a
button you press on the receiver unit instead of a jumper wire from
If you can find the receiver unit, inspect it for a button first and
follow the same programming method. In the case of the W-body, it was
a black wire with a white tracer....
