If your GM car radio says “Theftlock” on the display, it means the radio is locked and cannot be used. This can happen if your car is stolen or if you lose your car keys. To unlock the radio, you’ll need a special code.

To get the code, you’ll need to contact a GM dealership or a locksmith. The dealer should be able to give you the code for free, but a locksmith may charge a fee. Once you have the code, enter it into the radio and the theftlock will be released.

It’s an easy process, as long as you have the necessary information. To reach GM’s toll-free radio hotline, call 1-800-537-5140. You’ll be asked to provide your car’s radio identification number and a special dealer access code once you’ve connected. A 4-digit retrieval code will be given to you, which may be used to unlock your radio after this procedure is completed successfully.

Finding Your Radio Identification Code

  • Turn on your radio and insert your key in the ignition. Start your car as you normally would, or turn the key to “On” or “Accessory.” Then, to turn on the radio, press the power button on the radio’s volume dial. If the radio is locked, the digital display will show “LOC.”
  • Take a piece of paper and some writing utensils with you. To access your Theftlock radio, you’ll need to enter a four-digit numerical code. However, before you can do this, you must first write down two separate three-digit numbers that will be provided to you by punching specific buttons on the radio’s interface.
  • To find your radio’s identification code, press and hold buttons 1 and 4 until a 3-digit number appears on the display. This may take up to 10 seconds. Once it does, write down the numbers quickly and accurately – these are the first 3 digits of your ID code.
  • After pressing the AM/FM button, the second half of your radio identification number will appear on the display. On the radio’s screen, three more digits will show up after you press the button. These are the final three digits of your radio’s identification code. Keep track of the first three digits and these additional numbers.

Phoning in for Your Radio Retrieval Code

  • To retrieve your car radio’s code, dial GM’s toll-free radio hotline at 1-800-537-5140. You will be asked for your vehicle identification number and a special dealer access code. In return, you’ll receive a 4-digit retrieval code to unlock yourradio.
  • When prompted for a dealer access code, input “106010.” This is the most frequent code used by GM employees to reset stolen Theftlock radios. Carefully enter each digit, then press the # sign to submit your request.
  • When prompted, punch in the six-digit radio identification number of your vehicle. Using your phone’s keypad, input the two three-digit numerical codes you wrote down previously in a single unbroken sequence. Then press and hold the * sign to receive your radio retrieval code.
  • The automated voice on the other end of the line will recite a 4-digit code to you. Be sure to neat and precisely record these numbers down, as they are what you will use to unlock your radio. Once you have this information, feel free to hang up the phone.

Using Your Radio Retrieval Code to Unlock Your Radio

  • To figure out the first half of your radio retrieval code, press the hour button on the radio until the first 2 digits of the code appear. The number displayed will increase with each button press. Continue to tick off the hours in the hour position until they correspond to.
  • To view the last two digits of your retrieval code, hit the minute button. To finish entering the code, do the same thing you did to input the first two digits but this time with the numbers in the minute position. Before moving on, double-check that each digit of the code is correct.
  • To unlock your radio, press the AM/FM button. The display should now read “SEC,” meaning that the radio has been successfully unlocked. Switch on the radio and select your preferred audio input, and it should play as normal. It’s as simple as that!
  • You can clear an “INOP” message by leaving your battery on for 1 hour. Some Theftlock radios will shut down if you enter an incorrect radio retrieval code too many times, and when this happens, the display will read “INOP,” which stands for “inoperable.” To fix this problem, simply leave the key in the “On” position for a full hour and wait for the message to disappear.

How Do I Bypass Theft Lock on a GM Radio?

Theftlock is a security system that GM implemented in the early 1990s. It uses a radio’s identification number to lock the unit if it’s ever stolen, so that a would-be thief cannot reprogram the radio to work in another vehicle.

If you buy a used car that has this type of theft protection, you’ll need to know how to bypass it before you can use the stereo. Here are a few ways to do that:

  • Look up the radio’s activation code in the owner’s handbook if you have it. Because each automobile has its own activation code, you must discover the correct one for your car. After you’ve entered the code, turn on the stereo and try to unlock it again.
  • If you’re missing the manual that has the code, try searching online. More likely than not, somebody has already looked up and posted the code for your particular GM car model. Do a search using this formula: “[vehicle make] + radio unlock code.”

There are a few things to bear in mind while bypassing the Theftlock system on your GM vehicle radio. The first is to double-check that you have the correct activation code. If you input the incorrect code too many times, it may permanently lock up the device.
