After changing the battery, is the Toyota key fob required to be reprogrammed?

A remote key fob needs to be associated with your vehicle particularly in order to be secure.

This stops people who drive the same make and model of automobile as you from using their remote to access your car. You’ll need to reprogram the fob if changing the batteries has erased this connection or if it was somehow disrupted in order for it to once again recognize your automobile.

Standard programming sequence

Your key fob can typically be reconfigured by following this typical procedure:

Instead of starting and then returning to the locked position, turn the key into the run position. Repeat this multiple times.

You’ll typically hear a chime or other sound when you’ve cycled the key enough times. At that point, you can push the lock or unlock button on your key fob to hear another chime.

Taking Technology To New Levels

The all-new 2021 Toyota Sienna redefines the minivan segment with an emphasis on space and design to support a wider range of life phases and activities.

The fourth-generation Sienna is equipped with a variety of new technologies that increase the bar for style, safety, comfort, versatility, and fuel efficiency in its segment. It was designed and engineered in the United States. There are five different Sienna trim levels for 2021, with content varying significantly between LE, XLE, XSE, Limited, and Platinum. The first thing you should do when one enters your facility is to confirm the trim level, but there are also some other crucial elements you should be aware of.


The Camry, Avalon, Venza, and RAV4 all share Toyota’s Global Platform K (TNGA-K), which is the foundation for the 2021 Sienna. The significant use of hot-stamped sheet steel, ultra-high tensile strength steel, as well as aluminum components to minimize weight and provide a rigid body structure, is what gives the TNGA-K platform its inherent strength.

As an illustration, the sliding doors are made of lightweight metal. You are aware that repairing an aluminum door panel differs from fixing a steel door. Before moving forward, you must take into account the extent, location, and accessibility of the harm.

The plant that makes the Sienna binds the first and second steel sheets from the outside by using Laser Pinning Welding (LPW) on various portions of the chassis (the outer panel and reinforcement). Always use LPW close to spot welding. The outside of LPW resembles that of laser screw welding. The narrower diameter of the weld distinguishes LPW from Laser Screw Welding.

Use small diameter plug welding and adhere to the guidelines in the body repair handbook when doing LPW repairs. For more information, see “Precautions for Welding Document ID: RM100000001TW4D.”


The sealed Nickel-Metal Hydride (Ni-MH) hybrid battery for the Toyota Sienna’s SULEV status in 2021 is housed beneath the seats.

Both front-wheel drive and optional Electronic On-Demand All-Wheel Drive are offered for the Toyota Sienna. The Sienna uses a separate, rear-mounted electric motor that powers the back wheels as needed rather than the conventional transfer case and driveshaft. It functions perfectly, sending up to 80% of the driving force to the back wheels, reducing front wheel slide during off-the-line starts. Due to the lack of a transfer case or rear driveshaft, this arrangement also facilitates repairs.


Technology innovations abound in the 2018 Toyota Sienna to make driving safer and more convenient. The difficulty you face is that you must guarantee that those features are operational “as new” when you deliver the repaired car when one is brought in for collision repairs. We advise verifying any systems that might be impacted by an accident before you begin working and logging any difficulties you discover. Once the repairs are finished, verify the systems once more. new characteristics include:

  • Heated steering wheel and power tilt and telescoping steering column (Platinum)
  • rear-view digital mirror
  • When rear-seat occupants or cargo block the vision, it works like a regular mirror until the obstructions vanish at the touch of a switch, revealing the camera’s image from behind the car (optional on Limited and Platinum)
  • Dual power sliding side doors with hands-free kick-open and close1 (standard on XLE, XSE, Limited and Platinum)
  • Rear liftgate with hands-free operation (standard on XLE, XSE, Limited and Platinum)
  • Disabling or removing the kick sensor may be necessary in order to install a tow hitch receiver or other attachments close to the rear bumper.

What happens if the battery in my key fob dies while I’m driving?

This issue has been foreseen by automakers ever since the key fob was created. Nothing will happen if your key fob dies while you’re driving.
