I need to know if I can program my remote for my 1998 Seville without a
dealer? I have seen places to buy a new aftermarket remote that say they
will tell me how to do it, but I do not want them, I want the original
remotes to work the car. Can anyone help me? I maybe able to get a scan
tool, but did not want to have to do that. Someone told me that a series of
on, off with the key and hold down buttons on the remote might do it, but he
does not know exact process.
Thanks for any help,
On some cars, a series of magic button presses/ignition cycles (differening
depending on model and year) can do it, but on this particular car, it looks
like the remote transmitters can only be programmed with a Tech 2 scan tool.

It can be done without a Tech-2. The only problem is that nearly every year
GM, make and model, changes the procedure...
My 2000 Grand Prix required removing a fuse, locking and unlocking doors,
turning the key off and on and then holding the lock and unlock buttons on
Hopefully there is a GM Tech on this board or a locksmith that has the
procedure for your car...
I'll take a look and see if I can find the procedure for you.
I looked in the GM service info, Tech-2 is needed. This is likely due
to the settings memory setup, where if you use remote 1 it sets the
car up for that driver, remote 2 sets it up for the other driver.

Sorry about the misinformation. This year and newer do require the use of a
Tech-2, or some other device to program additional RKEs to the body control
A Tech-2 and a generic OBD-2 Code reader are not the same thing. The Tech-2
costs over $15K and does much more than read DTCs and reset the check engine
(MIL) light. You could build your own tool using an ELM322 chip and about
$30 worth of parts from RadioShack and a laptop with a serial port, but you
would still need to know the ODB-2 function code(s) to set the vehicle into
RKE Learning Mode. Not sure if you have any programming knowledge. Trust
me, it's not an easy task to reverse engineer GM proprietary ODB-2
If these are the original remote units for this vehicle, the codes are
already stored in the BCMs memory and they should not need to be
're-learned'. When you change the battery in the remotes, you need to
're-synchronize the remote to the vehicle by holding down the Lock/Unlock
buttons... You may want to try that first before you dump $40 per remote at
Does anyone have plans to make such a device? Or how about a different
device I can hook to my laptop. I am just plain afraid of throwing money
away and buying the wrong equipment for such a small problem. and yes, I
know I can go to my dealer for this problem and under $100.00 have this one
fixed. BUT what about the next time. My computer skills are great and
Mechanic skills are above average for a non certified mechanic.
Thanks again for all the help you can provide.
