The 1999 Acura model TL comes with an onboard radio that requires an anti-theft code to work. This isn't an issue in normal scenarios, because the code doesn't need to be entered everytime you start the car. If the car's battery dies, you must re-enter the code; the radio will shut-down and lock itself in the event of a power failure.
Check your Acura's original documentation. A card in the owner's packet displays the numbered code that unlocks your radio device. Keep this card, because it contains the serial number of your radio.
Check the serial number of your radio. The serial number is sometimes on the inside or outside walls of the glove box. If the serial number is not in either location -- and you have lost the card -- take the car to an Acura dealership. dealership. The dealership typically removes the radio from the car, because the serial number is located on the back of the radio.
Locate your car's vehicle identification number. This is 17-character number that identifies your car. Check your owner's manual, vehicle registration, insurance card or the sticker on the front windshield for the VIN.
Visit the Acura navigation-code website. The website requires your vehicle's VIN number, the serial number for the radio and the phone number and the zip code you had when you purchased the vehicle.
