I used to use dealer codes from previous dealerships I worked at. However, those dealerships no longer exist.

There are some unethical, greedy dealerships out there that will charge one hour of shop labor to do this. I used to work at one. One of the dealerships I worked at even charged this hour in addition to the normal labor for replacing a battery or alternator. If a dealership wants to charge a fee to unlock a radio, RUN!

I don't know, I can see them charging a .3 (18 minutes) or something like that. But an hour? No way.

Most shops or repair services have a 1 hour minimum charge for anything they do. To me this should be included in the alternator or battery change charge, not charge separately.

I just hope it's accurate and works. A poll might help, but I don't know how many may have this problem. Success or fail stories would greatly be appreciated.

Hi! I was very excited to see these instructions online because I just had my AC repaired and in the course of repairing it, the mechanic temporarily disconnected the electrical system and locked my radio. They weren't a dealership, so they didn't know how to reset it. They said I could take it to a dealership to unlock it, but I figure they will charge for that and the AC repair has wiped me out. But unfortunately I couldn't get the radio unlocked using these directions. Nothing happened at all during Step 2, so I couldn't go any further. Any ideas? Thanks.

You have to get your code before you lock up the radio. Only other option is to pull the radio and get the serial number and call it in for the code. I can't recall if the code is listed there as well. Been a while since I locked up and radio. I use a memory saver.

Hmmm, the source article was written in 2009. I betcha lunch for the next two weeks that these dealer codes will be called invalid when you call the 1-800 number. Has anyone else tried these instructions?
