My radio in my 05' Honda pilot stopped working. The anti-theft light flashes but there is no display. I pressed and held down 1 and 6 to reset it and it gave me U1112 and L1927. What is the code?

Question edited for clarity.
Question moved to model category.

To reset the anti-theft system on a Honda Odyssey: First try holding the panic button on your keyless remote for five seconds. Then, press the lock button twice. If that doesn't work, you can remove the fuse associated with the anti-theft system for one minute.

you can try the above for your 2000..if you get two 4 numbers have someone write them down. then go to the web site above. you'll need the VIN too.

no the unit has went into anti theft mode dealer can help reset

try taking the radio out and looking on the top for the parts number. call Honda and tell them what is going on and they will give you a 4 digit code that will reset the radio. i had the same problem with my 05 civic, did that and it worked for me.
good luck

In the newer Honda's there is a lock code on the radios when they lose power the code kicks in to prevent theft the reset code should be in your owners manual if it isn't call your locale Honda dealer.

In my case the solution was a fuse on the passenger side inside fuse box. It is not listed as a fuse for the radio but it is none the less. If your cigarette lighter isn't working either its the fuse. On my 2004 it was fuse # 9 a 15A fuse.
