How to open a key fob without breaking it

Fob cases are clipped together and the tabs break easily. Find the right release point first; never pry at a random seam.

1. Look for a release button or slide

Smart keys usually hide a mechanical emergency key. Slide or press the release on the back or end of the fob and pull the metal key out.

2. Use the slot behind the key blade

Where the emergency key came out there is often a small notch. Insert the key blade tip or a coin and twist gently; the two halves should separate along the seam.

3. Flip and remote keys

Many remote keys have a small notch on the seam near the key ring. Twist a coin or a thin flat tool in that notch, then work around the edge.

4. Note the battery orientation before removing it

Take a photo of the cell in place, then slide it out with a fingernail or plastic tool. Avoid metal tools on the circuit board.

5. Close it up and test

Press the halves together until all clips seat evenly, then test lock, unlock and start. If it doesn't work, see the troubleshooting checklist.

Opening methods vary by model. Your owner's manual shows the exact steps for your fob.

Coin cells are dangerous if swallowed. Keep new and used batteries away from children. Energizer warns that swallowing can cause serious injury or death in as little as 2 hours; if a battery may have been swallowed, get medical help immediately (US National Battery Ingestion Hotline 800-498-8666, as listed by Energizer).
