Car Alarms: lock/unlock buttons not working, 2008 toyota highlander, toyota highlander

Question
I have 2008 Toyota Highlander that has Checkmate Model KD-500+ installed.  In the last couple days my lock/unlock buttons on my remotes have not worked, I don't know if I hit something or not. But the remote start does work. The LED light was on. So I found the button under the dash and hit it and now the light is off but the remotes still don't work. Can you help?
BTW I bought this car with this already installed and don't have the factory remotes, I don't care about the security system, I just want the keyless entry.

Answer
Sorry, I don't supply remote programming here.
On this one, the best thing here is
to go to my installers forum at
www.installsupport.com and see if
my resident technicians there can assist
with this request

Good luck there.
