Steps to Replace

Opening the Key Fob

To replace the key battery for your Toyota RAV4, the first step is opening the key fob carefully. Depending on the type of key fob, the method may vary slightly.

For newer key fobs, a hidden metal key is included. This can be used to gently pry open the key fob case. Older key fobs may require a flat metal tool, such as a small screwdriver or a coin, to open the casing. Be careful not to use excessive force to avoid damaging the casing.

1. Locate the Release Mechanism: Identify the release button or switch on the key fob. For most models, this is usually a small, recessed button.
2. Release the Metal Key: Press the release button to remove the metal key from the key fob.
3. Open the Fob Casing: Use the metal key or a flat tool to gently pry open the key fob along the seam. Twist the tool slightly to separate the two halves of the casing.

Detailed visual guides and video tutorials can provide additional clarity on this process. For safety, consider viewing guides from reliable sources like Autorideup.

Swapping the Old Battery

Once the key fob is open, the next step is to carefully swap out the old battery with a new one.

1. Remove the Old Battery: Locate the battery inside the key fob. Typically, it is held in place by a small clip or contact points. Carefully lift the old battery out using a flat tool or by hand.
2. Insert the New Battery: Place the new battery into the key fob, ensuring that the positive (+) side is facing the correct direction as indicated within the fob. Align it properly with the contact points or clip.
3. Reassemble the Key Fob: Once the new battery is securely placed, snap the two halves of the key fob casing back together. Ensure that it clicks into place and there are no gaps.
