You can buy a remote for this on ebay.
When the service engine soon
light (Also called the check engine light or engine management light)
is turned on this is to alert you to the fact that Powertrain
Control Module (computer) has detected a failure somewhere in the
systems it controls you may not feel any difference in the way the
engine runs, this can be the transmission or the engine or emission
system, there are fault codes set in the modules memory for these
faults. What needs to happen now is to have the powertrain control
module scanned with a special tool called an OBD2 electronic engine
control scanner or a OBD2 code reader. Once the code(s) are read then
you must perform the diagnostics for each code and make the
appropriate repairs based on the findings of the diagnosis that was
performed, this is called doing "Pinpoint" testing.

I have had simlar issues. The first thing to try is to diconnect the positive lead from teh battery. Be careful as there are some issuesd surrounding OEM batteries in the 02. after about 30 secs reconnect the cable. This will "reset" your system and if it is just a glitch, the problem should be gone. If this does not fix the problem it is most likely your intrument cluster, however it can also be the BCM (Body Control Module). Have a dealer check it out for you. Before you buy a replacment part from the dealer chaeck out the prices at newgmparts.com or Rock Auto, both saved me 50% or more when I needed to have these items replaced.

Thank you for the advice, I purchased the keyless remotes online at Ebay. I am taking it to a mechanic close to my work, they offer free testing for the check engine light. After researching this make, model, year of car, alot of people said to check my gas cap to make sure it isn't worn out. This causes the sensor to react the check engine light. thank you for your help. :)
