I left my keys in the ignition and my battery went dead. Now my radio is flashing code..... I tried entering a random code which didn't work (of course).. Now it's flashing err 5 . Can anyone help with this. 2001 Cl

 

you cant enter a random code, you must enter the code specific to your serial number on the radio. you can obtain the serial number via instructions on the FAQ or get the link to get your code from the FAQ.

now that you entered too many wrong codes, it has locked you out. you must unplug the battery and reconnect it to get it out of the locked mode.

 

Open your glove box and there should be a sticker on the left side of the outside of the glove box. Enter that number sequence.

 

not everyone has it there. some have it under the fuse box under the hood. and some done have it anywhere at all (like mine).
but it wouldnt hurt to check.

 

Check the FAQ. Theres a sequence to enter to get the serial number, then call your dealer and get the unlock code.

 

Yeah I was told all Texas sold Acura's have it under the fuse box lid in the engine compartment.
