Changing the battery

Separate remote fob

  1. The remote is a small standalone unit. You will not need to touch the ignition key at all.
  2. Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
  3. Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
  4. Reassemble and test from a short distance.

A CR2025 is 20 mm across and 2.5 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

  1. This type has the buttons built into the key head. The cell is inside that head, between two clipped halves.
  2. Work a thin flat tool into the seam near the blade and twist; go round slowly if it does not open at once.
  3. Replace the cell with the same face showing, and make sure the rubber keypad sits flat before closing.
  4. Snap it closed and press each button. The car still starts with a dead remote battery on most of these keys, because the start chip needs no battery.

A CR1620 is 16 mm across and 2.0 mm thick. It is easy to confuse with the 20 mm CR20xx sizes, which will not fit.

A CR2025 is 20 mm across and 2.5 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)

  1. Find the small release on the edge or back of the fob and hold it while you pull out the metal emergency key.
  2. 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.
  3. 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.
  4. Reassemble, refit the emergency key, and check that the car sees the fob when you press start.

Subaru access keys usually hide an emergency key; with it out, the cover opens at the slot.

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.

Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
