ok, i was interested in putting a stock cd player from a 96 blazer into my blazer.. i found one on ebay, and it seems to be in good condition.. works and all, but i was wondering, will i have to get it unlocked? and if i do have to get it unlocked, what would i have to do.?

the person selling this item says they are not sure if its locked or not..

thanks.!

If the lock code is set, you'd need to take it to a dealer and have it unlocked. Depending on the dealers mood, sometimes they'll do it for free, otherwise they might charge a few bucks to do it.

do i have to have anything with me for them to unlock it, or do i just take the thing in there and say i need it unlocked?

Install it and take the vehicle in if it needs to be unlocked. I had to have mine unlocked once and it needs to sit with the key on for about an hour, they put in on a charger. You shouldn't need to take anything else, but should have vehicle registration just to be sure.

Try this.

if it's not the origional factory radio they will prob. need the serial number off the back of the radio too

heres a what if senario; say ur truck came w/cd player from the factory. u decided to put an aftermarket headunit in. lets say u want to sell the truck but u want to take out the aftermarket headunit and put the stock one back in. would u have to unlock the stock one again?

If the lock feature was turned on when the radio was taken out, it will have to be reset if you don't know the code. If the lock was turned off, you should be good to go.

Do some thread searching. I had almost the same problem I couldn't remeber my code. There is a thread in here that gives you step by step how to unlock the stereo. It is what the dealer would do. It is very easy worked for me.
