Locked radio


You will need to contact your local dealer with the Vin number of your truck & possibly the make of your radio. When a radio locks the dealer has the code to unlock the radio, just give them a call & you should have your radio working in no time.

Locked radio


You have to go to a chevy dealership to have them unlock the radio. They use a special code that will unlock the radio and then allows you to pick a new code. Hope this helps.

Sec lock on readio 1994 toyota celica disconnected


call the dealer with your VIN number, they will call the manufacturer and call you back with the code, alternatively, look in your owners manual in the front and rear page, some times dealers write them in there, also look in the radio pages they may have written there as well. Good luck

Need radio unlock code 99 olds aurora


They are all random codes that are stored in the radio. The radio can lock it's self with possible 10.000 differant codes. You will need to take it to the dealer to have them use the gm scaner to retreive the code that is in the radio then they call the gm headquarters and those egg heads give an unlock code for the car. All of the make since?

2004 Ford Escape Electrical problem


This is a problem with the alternator. Diode rectifiers and voltage regulator replacement will give this baby a 14.2 voltage output. In this 3L V6 SUV removal of the alternator requires removing the right tire, the right axis and undercovering to reach the 6G alternator. It is a 133mm rectifier with a motorcraft, The serpentine belt is better removed from the bottom. Also keep a bucket on hand to recover the oil from the transmission.
