If you own a late ‘90s or early 2000s model General Motors vehicle, you may have found out the hard way that your factory Theftlock radio is programmed to lock up if there’s any disruption in the battery. This can be a frustrating discovery, but don’t fret—all you have to do is enter a 4-digit retrieval code to unlock your radio and catch the end of your favorite song or call-in show. Most GM dealerships will try to charge you a lot of money for a radio retrieval code, but it’s possible to get it yourself in a just a few short minutes, provided you know the dealer code associated with your vehicle’s radio.
Finding Your Radio Identification Code
- If you don’t see the letters “LOC” but your radio isn’t working, the issue may lie elsewhere. Take your car to a qualified GM mechanic or car radio technician to have them diagnose the source of the problem. [2] X Research source
- GM Theftlock radios are designed to lock up automatically when the vehicle’s battery dies or becomes disconnected, though an electronic malfunction could also cause the Theftlock function to activate.
Tip: If the letters “RDS” appear on the display, it won’t be possible to unlock your radio yourself, as GM doesn’t offer retrieval codes for RDS radio units. In this case, you’ll need to visit a licensed GM dealership to have them reset your radio manually.
- You’ll be jotting down 3 sets of numbers in all, so make sure there’s plenty of room on your scrap paper.
- Try not to waste any time recording each set of numbers as they appear. Most GM Theftlock radios only give you 10-15 seconds to perform each step in the process before the display resets itself.
- If your radio doesn’t have 4 preset buttons, press and hold presets 2 and 3 instead. [4] X Research source
- Make sure the 2 sets of numbers are in the right order. If you enter your radio identification number incorrectly, your attempt to unlock your radio will fail.
- You’ll need to confirm this 6-digit radio identification code with GM over the phone in order to unlock your radio.

Phoning in for Your Radio Retrieval Code
- This is an automated line, so you won’t have to wait to talk to a live human being.
- You can call GM’s radio hotline for assistance at any time, day or night.
- Under normal circumstances, a locked Theftlock radio must be reset by a licensed GM dealer, who uses a special code known only by dealership personnel. By entering the code yourself, you can avoid the trouble and expense of paying to have your vehicle’s radio unlocked at the dealership.
Tip: GM has multiple dealer access codes, some of which are assigned to different dealerships for different vehicles. If the first code doesn’t work, hang up and try again using one of the following codes: 620529, 139010, 206053, or 202108. [8] X Research source
- Remember to read the numbers from left to right, and be careful not to accidentally include any other numbers or symbols. You should make a total of 7 button presses when it’s all said and done.
- If you don’t catch one or more numbers of the retrieval code, you’ll have no choice but to start the call over from the beginning.

Using Your Radio Retrieval Code to Unlock Your Radio
- If the first 2 digits of your radio retrieval code are “10,” for instance, you would need to push the hour button 10 times.
- On most Theftlock radios, you’ll find the time set buttons in the lower righthand corner of the radio interface.
- Holding the minute button will cycle through the numbers automatically so you don’t have to keep pressing it over and over again.
- You can repeat this process to resume use of your Theftlock radio any time it locks up unexpectedly.
- If your radio is still locked or refusing to cooperate after you’ve entered your radio retrieval code, your best bet is to schedule an appointment at a GM dealership to have it looked at by a professional.
- It’s important to record and enter your radio retrieval code correctly the first go-around to save yourself time, energy, and battery power.
Otázky a odpovědi komunity
Will the code work with an RDS-type radio?
Odpověď komunity
No, the RDS radios are programmed to read the vehicle’s VIN from the BCM (Body Control Module). If it is moved to a different vehicle or a different BCM is installed, it will «see» a different VIN and lock. It will have to be reprogrammed to the new vehicle’s VIN using a Tech II programmer. BCMs can only be programmed one time, and should not be moved from vehicle to vehicle. Not too many places other than GM dealers have the Tech II programmers.

I am not installing a radio in another vehicle, but in a boat. Will I still need to unlock the radio?
Saw a guide on how to deal with vehicles’ info-screen systems when they blacked out or froze. It’s a treatment for the symptom, not the underlying cause; they recommend that you take it to the dealer if it happens again, or even just once, to be sure everything is good to go. Anyway, for GM:
Mylink/Intellilink (2014-2016)
• Press the Home and Fast Forward buttons for at least 10 seconds
GM infotainment (2017-2019)
• Press the Onstar call button, then hang up.
Hopefully, this is useful to someone.

Tried the above instructions, nothing happened. I tried with radio power off and on, same result, it didn’t do a boot, it did keep changing radio stations but that was it. Not sure what I am doing wrong, I’m guessing you hold the buttons simultaneously for the 10 seconds.

Someone else mentioned a «reset procedure» from GM Canada, or something, I’ve found that works on my US ’17 ZR2.
- Put the key in and either turn it to ACC or turn it completely ON. Give it enough time for the infotainment system to boot (even if it’s a blank screen and it’s broken)
- Turn the car off and remove the key
- Otevřete dveře na straně řidiče
- Leave the door open for 2+ minutes
- You can now close your door and turn on your truck. The DIC should have reset

I had this issue happen for the first time 2 weeks ago and it’s happened once more since then. The Info screen blacked out but the rest of the screens worked. I did a similar reset procedure as you although I didn’t time how long you had to keep the door open. I so know that if you do it quickly though it won’t reset. I wonder if you have to wait long enough for the BCM to power down? I haven’t tried the procedure outlined in post #1 but I may try that if it happens again.

So, I’m running into this problem on my 18 Colorado. Undoing the negative battery cable did not work, and it doesn’t seem to be ‘bump’ dependant, so I don’t think it’s a connection somewhere.
So, I did a factory reset yesterday and it worked perfectly for a 30m drive to a restaurant, but when I came out it was back to going to the black screen every 2 minutes (repeatedly). It’s so annoying. I performed another factory reset, took a couple of 10 minute drives and no issue again. It’s so weird. Almost like a cache issue. And 10m is enough for it to reset 5 times, seriously, it does it repeatedly, non ******* stop. When I took it to the dealer it did it three times while they’re running the scan and getting the code. I’m going to keep digging as I have a light it background.
Of course the worst part is that buying a used one is much cheaper, but you don’t know if it has the issue as well and buying new from the dealer is $1,000 Plus.
