I just replaced the batteries in one remote, do I need to resycnronize it for it to work?

Yup If you dont know how, here.
1 Stand close to yor car
2 Press and hold the LOCK and UNLOCK buttons on the transmitter at the same time.
3 Hold the buttons for at least 5 seconds. During this time, the doors should lock and unlock once. This confirms the resyncronization.

I need the transmitters, I havent had the luxury of using keyles entery on this car. Does the horn sound when you push the lock button twice? Also can you open the trunk with the transmitter?

Horn doesn't sound, but the trunk will open. Lock does all 4 and the gas door lock. Unlock does the driver'* door with the first press, the other 3 and the gas door with the second press. And there'* a trunk button. Just like the one in your door, the car must be in park, but the ignition doesn't have to be on.

My 93 doesn't need to be re-synched after a battery change. Change and go.

No sych needed, and damn i've got good range again on the choosen remote. I don't have lights that flash or a toot of the horn, but maybe this summer i'll wire it up if our resident gearheads do it for me..

Gas door lock? I don't think i got that..

Not all did. I know Jseabert'* 93 SSE didn't get it, buy my 93 SSEi did. Not sure if it'* standard on the SSEi or not, but at least we know it was an option. If you lock your doors with the remote or the power switch in the car, the gas door locks. There is a manual release in the trunk near the LR strut tower.

mine has the gas door lock!
Makes a clunk noise when u un lock the doors!
Also my key pad just stopped working a few weeks ago, im gunna go try and Re-Sync it.
PS. I only have on key less entry transmitter.

Then get a new one! Or quick locking it in the car.

Whatever are you speaking of Jason?
No LOL i re programmed it today, had to do it the way it is in Tech Info,

Nope no re-programming on a 93. My wife just washed mine. That kinda screws up the batteries. I dryed it out with compressed air and changed the battery, the damn thing worked... figured it was toast.
When I got my bonnie it didn't have one. I managed to find one on e-Bay for $15, dealer wanted better than a $120 for it and another $75 to program it. Got a new remote for the $15 and took me less than 10 minutes to figure out how to program it. Saved myself a bundle

Well, for those interested I have two spare remotes for 1992-1995'*. I am asking $35 including shipping on the pair or $20 each. Both prices include shipping in the lower 48. For our Canadian bretheren add $5 for shipping. All prices are in US currency.
Only thing that is different is they have the Oldsmobile logo instead of Pontiac, but that is easily changed if you have non-working Pontiac unit. Otherwise they are identical to the original Bonneville units.
PM me if interested.
