I just bought an '03 Accord EX-L at a dealership last week. Everything is stock, including the anti-theft system.

The remote key didn't work at the time, so the mechanic cleaned it out, replaced the battery and re-programmed it to the car. Ever since then, the car randomly beeps (10 to 15 high pitched beeps from the dash, no horn). Sometimes, I'll be driving for a half hour and it won't beep at all, and other times it'll beep once every two minutes!

There aren't any warning lights, and the green key light isn't flashing. Just the anti-theft light next to the stereo. After doing research, I'm assuming I may have to re-enter the radio code? Also, does pressing the unlock button more than once disable it?
