2012 Cadillac SRX Key Fob Not Working? Here’s How to Fix It

Are you experiencing issues with your 2012 Cadillac SRX key fob? It can be frustrating when your key fob stops working, leaving you unable to remotely lock, unlock, or start your vehicle. Fortunately, programming or reprogramming your key fob can often resolve these problems. This guide provides step-by-step instructions to help you get your 2012 Cadillac SRX key fob working again, whether you have a working fob or are starting from scratch.

Understanding Common Key Fob Issues

Before diving into reprogramming, it’s helpful to understand why your 2012 Cadillac SRX key fob might be malfunctioning. Common causes include:

• Dead Battery: This is the most frequent culprit. Key fob batteries have a limited lifespan and will eventually need replacement.
• Desynchronization: Sometimes, the key fob can lose synchronization with your vehicle’s system, especially after battery changes or electrical issues.
• Faulty Fob: Less commonly, the key fob itself might be defective due to wear and tear or internal damage.

Reprogramming is a straightforward solution for synchronization issues and is often necessary after replacing a dead battery.

Programming a 2012 Cadillac SRX Key Fob When You Have a Working Fob

If you currently have at least one functional key fob for your 2012 Cadillac SRX, adding or reprogramming another fob is a relatively simple process you can do yourself. Follow these steps:

1. Turn off your Cadillac SRX. Ensure the vehicle is completely powered down.
2. Place the working key fob in the cupholder. This is important for the system to recognize a working remote is present.
3. Insert your vehicle key into the driver’s side door lock cylinder. This is the physical key slot on the exterior door handle.
4. Turn the key to the “unlock” position five times within 10 seconds. Make sure to perform these turns quickly and within the time limit.
5. Observe the Driver Information Center (DIC). After successfully completing step 4, the DIC display will show “Ready to Learn Electronic Key #2, 3, 4 ETC.” indicating the system is in programming mode.
6. Place the new key fob into the transmitter pocket. The transmitter pocket is located inside the center console, between the driver and front passenger seats. You’ll need to open the center console storage area and lift up the storage tray to access this pocket.
7. Press the ignition button. Do not start the engine; just press the ignition button briefly.
8. Wait for confirmation on the DIC. Once the new key fob is successfully learned, the DIC display will indicate it is ready to program the next remote.
9. Remove the new key fob from the transmitter pocket and press the “unlock” button on the fob. This confirms the programming.
10. Repeat steps 6 through 9 to program additional key fobs. If you have more remotes to program, follow the same procedure for each.
11. Exit programming mode. Once you have programmed all desired key fobs, press and hold the ignition button for ten seconds. This will exit the programming mode.

Your new key fob should now be programmed and working with your 2012 Cadillac SRX.

Programming a 2012 Cadillac SRX Key Fob When You Don’t Have a Working Fob

If you have lost all your working key fobs for your 2012 Cadillac SRX, the programming process is slightly longer and requires a wait period due to security protocols. Here’s how to program a new key fob in this situation:

1. Ensure your Cadillac SRX is turned off. The vehicle must be completely powered down.
2. Insert your vehicle key into the driver’s side door lock cylinder. Use the physical key slot on the exterior door handle.
3. Turn the key to the “unlock” position five times within 10 seconds. Perform these turns quickly within the time limit.
4. Observe the Driver Information Center (DIC). The DIC will display “REMOTE LEARN PENDING, PLEASE WAIT.” This indicates the system is entering a security wait period.
5. Wait for ten minutes. Allow the system to wait for the full ten minutes. The DIC display will change to “PRESS ENGINE START BUTTON TO LEARN.”
6. Press the ignition button. Press the ignition button briefly (do not start the engine). The DIC display will again show “REMOTE LEARN PENDING, PLEASE WAIT.”
7. Repeat steps 5 and 6 two additional times. You will need to wait for ten minutes and press the ignition button a total of three times. This process is necessary for security reasons. After the third cycle, any previously known remotes will be erased from the system’s memory.
8. The DIC display should now show “READY FOR REMOTE #1”. This indicates the system is ready to learn a new key fob.
9. Place the new key fob into the transmitter pocket. The transmitter pocket is in the center console, just like in the previous procedure.
10. Press the ignition button. Press the ignition button briefly.
11. Wait for DIC confirmation. Once the key fob is learned, the DIC will indicate it’s ready for the next remote.
12. Remove the new key fob and press the “unlock” button. Confirm the programming by pressing the unlock button on the new fob.
13. Repeat steps 9 through 12 to program additional key fobs. Program any additional remotes you need using the same steps.
14. Exit programming mode. Press and hold the ignition button for ten seconds to exit the programming mode once all key fobs are programmed.

Your new key fob should now be programmed and operating your 2012 Cadillac SRX.
