Last updated:
If the key fob on your Saab 9-5 (9600, 1998–2010) has gone weak or the central locking has become intermittent, the coin cell inside is almost certainly flat. Note that the 2001–2010 key uses a less common CR1632 cell — check before you buy.
Battery First — What You Need
- A CR1632 coin cell (not the usual CR2032 — the Saab fob takes the thinner CR1632).
- A small flat screwdriver.
Replacing the Cell
- Ease the fob case apart at the seam with a screwdriver.
- Remove the old cell (don’t touch the terminals).
- Fit a new CR1632, observing the correct polarity.
- Close the case and check the remote locks and unlocks the car.
Lost Key or Adding a Spare
A cell swap keeps the existing coding. Key programming needs a diagnostic tool (up to 4 keys; all keys, including existing ones, must be reprogrammed together) — a dealer or Saab specialist handles that.
If a Fresh Cell Doesn’t Help
- Make sure it’s a CR1632 — a CR2032 is too thick to seat.
- Check the polarity.
- Still intermittent? A receiver fault can store a code — look it up on autodtcs.com.
Frequently Asked Questions
What battery does the Saab 9-5 key use?
The 2001–2010 fob takes a CR1632 — thinner than the common CR2032.
Do I need to reprogram the key after the swap?
No — the coding is retained for a battery change.
Can I program a new key myself?
No — programming needs a diagnostic tool, and all keys must be re-coded together.
Why won’t a CR2032 fit?
It’s too thick — the holder is sized for the thinner CR1632.
If the fob stopped working after a battery disconnection, see our 9-5 battery guide.
