The remotes for the 2004 and older model are rectangular, and should have a Lock and Unlock button on the front, and a small, red, square Panic button on the back. The 2005-up Tacoma uses Toyota's newer-style remote, which is much more organic looking, and has the Panic button on the front. But, although I've seen a few of those Tacomas with factory keyless entry, I've never seen one with a factory alarm. Why do you think you have a factory alarm? Are you seeing a rectangular panel in the dash, with a red light, that says "SECURITY?" Does that light also have another small opening next to it, on the same panel? If you do see another opening next to the security light, that's the microphone for a glass break sensor.............and a good indication that it's a dealer-installed alarm, not factory original. I think it's called a VIP3200 or something like that. (VIP is for Vehicle Intrustion Protection.) It's a Toyota alarm, but installed by the mechanics at the dealership. To further add to the confusion............there's a VIP alarm for cars that already came with factory keyless, and in that case, you'd be shopping for the factory remotes that come with any Tacoma. I think (maybe, not sure) there's also a system for Toyotas that never came with any remotes at all, and so this alarm comes with its own remotes. I don't know how (maybe look at the Tacoma forums?), but you probably want to figure out if your Tacoma ever came with factory keyless in the first place. Good luck! P.S. Have you already had your truck inspected for the frame recall? Before you invest money in remotes, have the dealer inspect the frame, because they are buying back a lot of these trucks.
