Losing or damaging your car key fob can be a major inconvenience. If you’ve found yourself with a broken key fob for your 2015 Cadillac SRX, or had to replace your number one fob, you might be relieved to know that programming a new key fob yourself is possible. This guide will walk you through the process of programming a new key fob for your 2015 Cadillac SRX, even if you don’t have a recognized transmitter. This procedure will clear out all previously programmed key fobs, so you’ll need to reprogram all of your transmitters at the same time.
Before you begin the programming process for your 2015 Cadillac SRX key fob, please take note of the following important considerations:
- Complete Unlearning: This procedure will erase all previously programmed transmitters. Ensure you have all the key fobs you intend to use with your vehicle present during the programming process.
- Time Commitment: Be prepared to dedicate approximately 30 minutes to complete the entire programming sequence.
- Maximum Transmitters: Your 2015 Cadillac SRX can be programmed to recognize up to eight transmitters in total.
- Transmitter Only Programming: This procedure is specifically for programming the vehicle transmitter functions (remote lock/unlock, etc.). It does not handle immobilizer information related to vehicle starting, which is managed separately by the Body Control Module (BCM) and Engine Control Module (ECM).
- Isolation of Existing Transmitters: If you still have working key fobs, it’s crucial to keep them far away from the vehicle during this procedure. Even opening the case as if to replace the battery can help ensure they don’t interfere. Failure to do so may inadvertently switch the system to the “Adding Transmitters” procedure instead of the “Replacing #1 FOB” procedure.
Here is the step-by-step guide to program your 2015 Cadillac SRX key fob when you are replacing the #1 FOB or programming without a recognized transmitter:
-
Initiate Remote Learn Mode: Locate the key cylinder above your rear license plate. Insert your vehicle key into this cylinder. Turn the key to the unlock position five times in rapid succession within a 10-second timeframe. After completing this step, observe the Driver Information Center (DIC) display in your vehicle. It should show the message “Remote Learn Pending, Please Wait.” Allow ten minutes for this process to complete.
-
First Learning Cycle: After the ten-minute wait, the DIC will update to display “Press Engine Start Button to Learn.” Press and release the ignition mode switch (start/stop button). The DIC will once again show “Remote Learning Pending, Please Wait.” Wait for another ten minutes.
-
Repeat Learning Cycles: Repeat step 2 two additional times. This means you will perform step 2 a total of three times, with each ten-minute waiting period. After the final ten-minute period, all previously programmed transmitters will be erased from the system’s memory. The DIC will then display “Ready for Remote #1.”
-
Prepare New Transmitter: If you disassembled your new transmitter earlier (for example, as suggested to isolate a working fob), reassemble it now.
-
Position Transmitter in Pocket: Inside your center console storage bin, locate the indent under the rubber liner. Place your new transmitter into this indent with the buttons facing downwards. If a large keyring is preventing the transmitter from sitting fully in the indent, remove the keyring temporarily to ensure proper placement. Proper placement in this pocket is crucial for successful programming.
-
Program Transmitter #1: With the new transmitter placed in the pocket, press and release the ignition mode switch one more time. When the transmitter is successfully learned, the DIC will indicate that it is ready to program the next transmitter.
-
Program Additional Transmitters (Optional): If you have additional key fobs to program, remove the transmitter from the pocket and press the unlock button on the fob you just programmed to confirm it is working. Then, repeat steps 4 through 6 for each additional transmitter you wish to program.
-
Exit Programming Mode: Once you have programmed all desired transmitters, press and hold the ignition switch for approximately 5 seconds to exit the key fob programming mode.
By following these steps, you should be able to successfully program a new key fob for your 2015 Cadillac SRX. This DIY procedure can save you a trip to the dealership and get you back on the road quickly with a functioning key fob.
