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.
Look for a screw on the back or a notch on the edge. Remove the screw if present, then twist a coin in the notch to split the case.
Lift the old coin cell out and press the new one in with matching orientation.
Reassemble and test from a short distance.

This key takes two CR2016 cells. Change both at the same time and stack them the way the old pair sat; mixing a fresh cell with a tired one shortens the life of the new one.

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.
Work a thin flat tool into the seam near the blade and twist; go round slowly if it does not open at once.
Replace the cell with the same face showing, and make sure the rubber keypad sits flat before closing.
Press the head together until it clicks and test the buttons. The transponder chip that lets the car start is separate from the battery, so starting should not change.

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.

Smart key (push-button start)

Start by freeing the hidden metal key: there is a latch or slide on the case, and the blade comes out once it moves.
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.
Note which side of the old coin cell faces up (usually the side with the writing), lift it out with a plastic tool, and press the new one in the same way.
Close the case until it clicks all the way round, put the metal key back, then try the buttons and a push-button start.
