It depends on which make and model you have.
hi i need to find the unlock code for jaguar S-Type stereo.
To enter the code for a Renault Megane stereo, first, turn on the ignition and the stereo. If the display shows "CODE," use the preset buttons (1-4) to input the four-digit code. Press the "OK" or "Enter" button to confirm the code. If entered correctly, the stereo will unlock and begin functioning normally.
If I remember, turn the stereo on, enter the code using the 6 preset buttons. After the beep, turn the stereo off. Then turn the stereo on and it should be OK. I just pulled my radio to get into the dash.
Try disconnecting from the battery the neutral cable for approx 11 minutes. Akhtar
First you need the code to enter. Check your owner's information for a business card with Anti-Theft Radio Identification Card at the top. There is a 5 digit code. Enter that using the number keys of your radio when you see "Code" on the digital screen of the stereo. If you don't have the code, you need to get it from a Honda dealership. You will need the system's serial number to get this.
When you enter the security code wrong on a Citroen Saxo car stereo, it will display an error. If error 9 is displayed on your stereo, you have entered the wrong code nine times and your system is blocked. You will have to wait to enter the code correctly.
To enter a stereo code on a 2006 Acura, first turn on the ignition and the radio. If the radio displays "CODE," use the preset buttons (1-6) to input the code. Press the appropriate button for each digit of the code, and then press the "AM/FM" or "Enter" button to confirm. If the code is correct, the radio will unlock and resume normal operation.
I think the code is located in the fuse box under the hood.
I don't know about Jaguar specifically, but usually you bring the ownership to the dealer, and they will look it up on their computer for you.
I had a similar problem when I purchased a second hand stereo for my Jag but the code that was given was wrong. I contacted a car audio firm and they decoded the radio for me at a cost of around
You need to re-enter the code for your stereo which can be found in the manual that should have been supplied with your car
