Anti-Theft Radio Unlock?

'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?

I would be a little nervous trusting any of the online sites that offer online codes. After all, the entire purpose of having the code is to prevent theft. What good would the audio security system be if any thief could get the universal unlock code online?

You will have to take it to the dealer to get it unlocked. In the future, you should record the radio unlock code and put it in the same place you store the key code information. - You do have the key code information stored somewhere you know, right? ;-)

I have the little aluminum tabs that came with the keys (multiple yotas) --- recently took one to dealer to have key cut for a 90 4Rnr (my daughter now has) and, $7 later it, would NOT work. Had old worn key duped at HD for $2 and it worked fine. Why would't the original code cut key work? Old key worn pretty smooth and sharp. You'd think the key tab would have part of VIN on it too --- they all look the same so there is no way to tell which vehicle unless you scratch something into the back of them.

Yota seems to have dropped the anti-theft radio thing now - thank goodness. Doubt there was ever much marked for stolen OEM yota radios - just messes up original owners who keep them past the battery life!

The replacement key didn't work because it fit the original pin pattern perfectly (assuming that the key was cut correctly), while the original key and cylinder pins were worn. If you were to file down the replacement key so the wear matched the original key, it would probably have worked.

I agree, after Toyota dropped the 7 band graphic equalizer in Celicas and Supras, the demand for OEM radios seemed to drop off quite a bit.

I left my little key-code tag on the dealer's paper stock-number tag. And I have a fairly fresh Original key on the same ring.

You have the key code, but if the dealer's key punch was worn or out of alignment, or the person punching it was clueless (they couldn't read the numbers right in the punch codes book, or didn't know how to work the dials) it could easily punch a bad key.

The best way to get a 'factory fresh' key is with a pair of calipers

- the locksmith knows the height increments of the tumbler pins or wafers, reads each notch on the old key with calipers, adds in for the wear, and sets the punch heights on his key-punch machine by hand.

Problem is, now the interior parts of the locks are all worn out, and don't know how to deal with a fresh key - seriously. The lock and the most-used keys wear into each other. Some locksmiths have the internal parts to rebuild the wear parts of the cylinders, but the labor costs can eat you alive on work like that.

This is why the dealers sell complete 'sets' of replacement lock cylinders (Doors, trunk/hatch, fuel door, ignition and glove/console) keyed alike with the master and valet keys - so you can quickly re-key the whole car with fresh.

Called dealer I bought it from and they said they would put their computer reader on the car and reset the radio for $85. Guess I'll call back when someone smarter is there --- they merely need to enter correct key sequence and a 6 digit code. Service writer was sure he was right!
