'93 4Rnr battery went dead after 4+ years. I recall setting the radio anti-theft code but (argh) never wrote it down. Tried all my favorite PIN 3 digit combos. After 9 tries security lock went from SEC to it now it says HELP. I did find a 6 digit unlock sequence but how do you enter it? --- can"t get it to allow entry of those digits.
I understand dealer can unlock usually for a cost but not sure real value on a '93 OEM radio. It worked fine before the battery konked out. Anyne ever reset with the code and do you know the keys to use to enter?
There are also several online sites that offer the unlock code for a fairly reasonable $25 --- do they work or is it crawl to dealer?
