Lost your 2008 Toyota Avalon key fob or need to program a new one? The good news is, for 2008, 2009, 2010, 2011, and 2012 Toyota Avalon models, you can program the remote portion of your key fob yourself, right at home! This guide provides you with easy-to-follow instructions to get your keyless entry working again in no time.
It’s important to understand that this DIY programming method is for the remote control functions only – locking and unlocking your doors, and activating the panic alarm. You will still need to visit a Toyota dealership or a qualified automotive locksmith to have the physical key cut and the transponder chip programmed if you need a key that starts the engine. This procedure focuses solely on the remote functions of your key fob, not the immobilizer or smart key features. This method is specifically for the standard remote key, and will not program Smart Key units.
Ready to get started? Follow these steps carefully:
-
Preparation is Key: Ensure the driver’s side door is open and unlocked, and that the key is removed from the ignition switch before you begin. It’s crucial to perform the next steps swiftly and within the specified timeframes.
-
Ignition and Key Dance: Within 5 seconds of starting, insert your key into the ignition switch and remove it twice.
-
Door Cycling: Within 40 seconds after the previous step, close and then open the driver’s door twice.
-
Repeat Ignition and Key Dance: Insert the key into the ignition switch and remove it once again.
-
Repeat Door Cycling: Within 40 seconds, close and open the driver’s door twice again.
-
Final Ignition Insertion and Door Closure: Insert the key into the ignition switch and close the driver’s door.
-
Programming Mode Selection: Now, you need to select your programming mode.
- Retain Original Codes: Switch the ignition ON then OFF once to program a new remote while keeping any previously programmed remotes working.
- Erase Original Codes: Switch the ignition ON then OFF twice if you want to erase all previously programmed remotes and only program the new one(s). This is a good security measure if you suspect a key fob has been lost or stolen.
-
Confirmation and Remote Registration: Remove the key from the ignition. At this point, the system should automatically lock and unlock the vehicle. The number of times it locks and unlocks indicates the mode selected: once, twice, or even five times. It will then cycle the locks one to four times slowly to show how many remote transmitters are currently registered in the system.
-
Remote Button Pressing Sequence: Within 40 seconds, take the remote you wish to program and press and hold both the LOCK and UNLOCK buttons simultaneously for 1.5 seconds.
-
Final Lock Button Press: Immediately after releasing the LOCK and UNLOCK buttons, press the LOCK button by itself.
-
Confirmation of Programming: The vehicle should now lock and unlock once to confirm successful registration of the remote. If it locks and unlocks twice, it indicates that the registration has failed, and you may need to repeat the process.
-
Programming Additional Remotes (Optional): If you have more remotes to program, repeat steps 9-11 within 40 seconds for each additional remote. Remember that a maximum of 4 remote transmitters can be programmed to your 2008 Toyota Avalon.
-
Exiting Programming Mode: To exit the programming mode, simply open the driver’s door.
By following these instructions carefully, you should be able to program your 2008-2012 Toyota Avalon key fob remote quickly and easily. This DIY method can save you time and money compared to going directly to a dealership for remote programming.
For those needing to purchase a replacement remote, you can find options online from reputable sources specializing in car remotes.
