I've personnally never seen a keyless entry standalone system on a Camry, Toyota puts a security system. Mine didn't come with keyless from the factory only power lock and windows equipped factory. My buddy's 95 corolla came factory equipped with security and he has a little indicator in the center console that says security with a flashing light. Conclusion: Odds are, you don't have it.
Now the next step is finding a good system to install on your car. After doing my research for my system, I opted for a DEI keyless entry/remote start/alarm system. I talked to several techs who installed these systems at big stores and all told me DEI. Some even told me they wouldn't even touch the system if it wasn't a DEI!!! As for installing it, if you decide to tackle it on your own, here is the website:

I'm not sure what is your vehicles trim, so you can go ahead and enter all that info... Or, if you really want to make your friends go crazy, do like I did and get a kill switch


I have so much fun when someone comes in my car and I challenge them to start her and she doesn't... And hide the switch on the left side of the steering to make it seem like you have a "magic touch" to make the car start!!!
