Can't Unlock Theftlock
 

I installed a replacement used Monsoon head unit and followed the procedure in the sticky and called in to get an unlock code. The four digit code I was given is 0xxx; however, there is no zero on the keypad - only 1 through 6. Nor can I get the numbers to come up pressing the HR and Min buttons.

What to do???

Also is the unit to be turned off or left on after obtaining the two three digit codes? I've tried both ways but it doesn't seem to affect the fact that I can't come up with a zero as the first digit of my four digit code.

Try these dealer unlock codes, one of them might work for you.

I used the first one and it worked. That's where I got the four digit unlock code. The problem is the first digit of the unlock code is a zero, and there is no zero on radio buttons. Or there is another way of entering the numbers. :confused:

Try the 2nd one and maybe a different 4 digit code will come up. I've never done this before so I really can't help you about entering the 4 digit code. I found the dealer codes in the Monsoon FAQ.

Try this:

With the 4 digit factory back-up code in hand perform the following steps.

1. Press the Minute button and 000 will appear on the display.
2. Press and hold the Minute button until the last two digits agree with the back-up code.
3. Press and hold the Hour button until the first one or two digits agree with the back-up code.
4. Press the AM/FM push button after you have confirmed that the code matches the factory back-up code you wrote down. If "SEC" appears on the display, the radio is now operable and secured. (The original, unknown user code is still stored in the radio.) If "REP" appears on the display, repeat steps 1 through 4.
5. If the display shows "- - -" this indicates that the unknown user code has been removed. (The "- - -" will go off after a short time and the Theftlock code has been erased, Theftlock has been disabled and the radio should function normally.)

Tried it and it gave me the same unlock code. Good idea, though.

Ok, I'll go out to the car now and see if I can get it to come up this way ... backwards, as it were.

I posted the procedure above to enter the 4 digit code but I don't know if you saw it.

I see you did, let me know if it works.

Worked!!! Thanks, man!!

That's cool, I'm glad it worked for you.
