Changing the battery
Separate remote fob
- A separate fob has no key blade inside, so it opens with nothing but a coin or a small screwdriver.
- Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
- Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
- Reassemble and test from a short distance.
A CR2032 is 20 mm across and 3.2 mm thick. CR2032, CR2025 and CR2016 share the same width but not the same thickness, so a swap between them can leave a loose contact or a case that will not close.
Key with remote in the head
- This type has the buttons built into the key head. The cell is inside that head, between two clipped halves.
- Find the seam around the head. Twist a coin or small flat screwdriver in the notch at the blade end or side until the halves part.
- Inside you may find a small circuit board in a tray. Lift the board out if the cell is underneath, swap the cell with the same side up, and refit the board.
- Close the head, check there is no gap, and try the buttons.
A CR2016 is 20 mm across and 1.6 mm thick. CR2032, CR2025 and CR2016 share the same width but not the same thickness, so a swap between them can leave a loose contact or a case that will not close.
Smart key (push-button start)
- Most push-button fobs hide a metal backup key. Press or slide its catch and draw the key out first.
- The gap left by the metal key usually has a pry point. A slow twist with a thin flat tool (tape on the tip saves the plastic) opens the two halves.
- Before you take the old cell out, look at its face. Put the new cell in with the same side showing, and avoid touching both faces at once.
- Close the case until it clicks all the way round, put the metal key back, then try the buttons and a push-button start.
On most Toyota smart keys the metal key slides out after you press a small release, and the case opens at the slot it leaves behind.
A CR1632 is 16 mm across and 3.2 mm thick. It is easy to confuse with the 20 mm CR20xx sizes, which will not fit.
A CR2032 is 20 mm across and 3.2 mm thick. CR2032, CR2025 and CR2016 share the same width but not the same thickness, so a swap between them can leave a loose contact or a case that will not close.
A CR2450 is 24.5 mm across and 5.0 mm thick, much fatter than a CR2032. A thinner cell will rattle and lose contact, so buy the exact size.
Keep spare coin cells away from small children. A swallowed coin cell can burn the throat within hours; if it happens, go to an emergency room at once.
