The original radio has just been put back into Ka, after some time with a replacement part. Radio does not accept key code, and reverts to wait 30 after each entry. Upto 6 attempts now, and concerned at 10 max limit. What can I try next?

First , check that you are using the correct code. Ask another question quoting the SERIAL NUMBER ( should be M******.

Check also that you are entering it correctly.Instructions here :http://www.davidsonelectronics.co.uk/code_entry.htm

If you are entering the correct code , in the correct sequence and it still doesn`t work, then it looks as though the radio has been recoded to a different number in the past by a Radio Decocoder and will have to be taken in to be read + recoded again.
It might be cheaper just to buy another off Ebay with a code.
