Is your 2011 Toyota 4Runner key fob not working reliably? Often, the first culprit is a dead battery.

This guide will walk you through not only replacing the battery in your 2011 Toyota 4Runner key fob but also how to reprogram it if necessary.
While battery replacement is simple, sometimes after changing the battery, or if you have a new key fob, you might need to reprogram it to your vehicle. Follow these steps to program your 2011 Toyota 4Runner key fob.
Step-by-Step Guide to Program Your 2011 Toyota 4Runner Key Fob
This programming procedure should be completed relatively quickly, so ensure you read through all the steps before beginning.
Step 1: Vehicle Preparation
Before you start, make sure of the following:
- The key is OUT of the ignition.
- All doors are CLOSED.
- The DRIVER’S DOOR is the only door that is OPEN and UNLOCKED.
Step 2: Initiate Programming Mode – Part 1
- INSERT the key into the ignition. Do NOT turn the key.
- REMOVE the key from the ignition.
Step 3: Initiate Programming Mode – Part 2
You need to perform the following actions WITHIN 40 seconds:
a. Locate the power lock switch on the driver’s side door panel. Perform FIVE lock/unlock cycles using this switch, beginning with the LOCK action. Maintain a consistent pace, aiming for approximately one cycle per second (one cycle equals one lock and one unlock).
b. CLOSE the driver’s door, and then OPEN it again.
Step 4: Initiate Programming Mode – Part 3
Again, you must complete these steps WITHIN 40 seconds:
a. Use the power lock switch on the driver’s door panel to perform FIVE lock/unlock cycles, starting with the LOCK action. Keep a steady rhythm of about one cycle per second.
b. INSERT the key back into the ignition.
c. TURN the ignition to the ON position (do not start the engine), and then turn it back to the OFF position. The number of times you perform this step determines the programming action:
* **ONCE**: Retains currently programmed remotes and adds new remotes.
* **TWICE**: Erases all existing programmed remotes and programs the new remote(s) only.
* **THREE TIMES**: Checks the number of remotes currently programmed to your vehicle.
* **FIVE TIMES**: Erases all existing programmed remotes.d. REMOVE the key from the ignition.
Step 5: Confirm Programming Mode Entry
WITHIN 3 seconds of removing the key in the previous step, the power door locks should automatically cycle LOCK then UNLOCK. This indicates that your 2011 Toyota 4Runner has successfully entered Programming Mode.
Step 6: Program Your Remote
Complete the following steps WITHIN 40 seconds:
a. On the key fob you wish to program, PRESS and HOLD both the LOCK and UNLOCK buttons simultaneously for 1 second.
b. Immediately after, PRESS and HOLD the LOCK button for 2 seconds.
The door locks should cycle **LOCK** then **UNLOCK** again to confirm successful programming of this remote.Step 7: Program Additional Remotes
If you have more remotes to program, REPEAT Steps 6a and 6b for each additional key fob.
Step 8: Exit Programming Mode
To exit the programming mode, simply CLOSE the driver’s door.
Step 9: Test Your Remotes
Thoroughly TEST all programmed remotes to ensure they are working correctly. Programming is now complete. If any remotes are not functioning, repeat the entire programming process carefully from Step 1. Sometimes, ensuring a fresh 2011 Toyota 4runner Key Fob Battery is installed before programming can resolve issues.
