Losing or needing to replace a key fob for your 2010 Acura TSX can be a frustrating experience. The good news is that programming a new or existing key fob for your vehicle can often be done yourself, without a trip to the dealership. This guide will walk you through the step-by-step process to program your 2010 Acura TSX key fob, saving you time and money.
Step-by-Step Guide to Program Your 2010 Acura TSX Key Fob
Before you begin, ensure you have all your key fobs you wish to program with you. The system can store up to four transmitter codes, and programming a new one might erase the oldest code in the memory. Also, it’s crucial to keep the timing precise between each step for successful programming.
Here’s how to program your 2010 Acura TSX key fob:
-
Turn the ignition to the ON position (II). This is the position right before you would start the engine.
-
Within 1 to 4 seconds, press the LOCK or UNLOCK button on the key fob you are programming. Make sure to aim the transmitter towards the keyless receiver unit. This unit is typically located behind the driver’s side of the dashboard.
-
Within 1 to 4 seconds, turn the ignition switch OFF.
-
Within 1 to 4 seconds, turn the ignition switch back to the ON position (II).
-
Within 1 to 4 seconds, press the LOCK or UNLOCK button on the key fob again, aiming at the keyless receiver unit.
-
Within 1 to 4 seconds, turn the ignition switch OFF.
-
Within 1 to 4 seconds, turn the ignition switch back to the ON position (II).
-
Within 1 to 4 seconds, press the LOCK or UNLOCK button on the key fob, directed at the receiver.
-
Within 1 to 4 seconds, turn the ignition switch OFF.
-
Within 1 to 4 seconds, turn the ignition switch back to the ON position (II).
-
Within 1 to 4 seconds, press the LOCK or UNLOCK button on the key fob, aiming at the keyless receiver unit.
-
Listen for the door locks to cycle. Within 1 to 4 seconds after pressing the button in step 11, you should hear the sound of the door lock actuators. Immediately press the LOCK or UNLOCK button again to confirm the code storage. If you don’t press the button again after hearing the locks, the programming will not be saved.
-
Program additional key fobs (if needed). Within 10 seconds of hearing the door locks cycle, if you have other key fobs to program, aim each transmitter at the keyless receiver and press the LOCK or UNLOCK button. You should hear the door locks cycle after each successful programming. You can program up to two additional key fobs at this stage.
-
Turn the ignition switch OFF and remove the key from the ignition.
-
Test all programmed key fobs to ensure they are working correctly by locking and unlocking the doors, and activating the panic alarm if applicable.
Important Notes for Successful Programming:
- Timing is critical: Ensure you adhere to the 1 to 4 second time limit between each step. Too slow or too fast, and the programming sequence may fail.
- Battery Condition: Make sure the battery in your key fob is in good condition. A weak battery can sometimes cause programming issues.
- Quiet Environment: Listen carefully for the door lock actuators to cycle in step 12. A quiet environment will help you hear this confirmation sound.
- All Doors Closed: Double-check that all doors, the hood, and the trunk lid are fully closed before starting the programming process. Windows should also be rolled up.
- Programming Mode Cancellation: If you enter programming mode and do not press a remote button a second time after hearing the door locks, or if you turn the ignition OFF prematurely, the programming for all remotes will be cancelled, and you will need to start again from step 1.
By following these steps carefully, you should be able to successfully program your 2010 Acura TSX key fob. If you encounter difficulties, double-check each step and timing, or consider seeking assistance from a professional locksmith or your Acura dealership.
