Key Fob battery replacement

I have a 52 reg Saab 9-5 3.0 Tid Arc and the display says the key fob battery needs replacing, according to the car manual this is a job for the dealership.
Is this not just a straight forward battery replacement I can do myself?

A pushpin inserted into the hole with a push pry motion pops mine right off with no damage.

Just push a small diameter allen key into the hole and it will pop open. Then gently open from the side with a finger nail or spreading knife.Replacement battery required is a CR1632.

CR1632 is the battery you need for your key fob. A small paperclip inserted into the hole on the side of the fob with a bit of force will open the panel on the back. Make sure your car is closed and then you press unlock 5 times to synch it with your car again.

2005 Saab 9-3 Convertible randomly unlocks (mostly the trunk) with horn beeps. Key fob will not lock/unlock car (battery replaced). These might be separate issues.

If this only happens when the key fob is close enough for the car to "hear" the signals transmitted from it then chances are the fob is failing. The FOB will have to be taken apart, cleaned and inspected for contamination/corrosion/stress cracks.
If the car does this on it's own even when the FOB has no battery or is too far away to be heard, then the problem could be internal on the TWICE (Theft Warning Module) or a power lock switch.
Since you said the horn beeps I would say it is most likely a FOB inadvertently transmitting signals even when you're not pushing buttons. Repair or replace the fob and you should be okay.

I changed the key fob battery (twice) in my 2004 9-3 but still get the Replace Battery indicator - - and cannot lock using the remote... although unlocking works fine. How can I reset the indicator t

Did you already re-sync?
"After you change the battery, be sure to put the key in the ignition and start the car so it will re-sync."
"You sync it with the key in the ignition turned to 'ON' and press the UNLOCK button 7-10 times."

This suggests removing key with gear lever in Reverse:

My immobilizer does not recognise my key fob

Put key in ignition.
Press unlock button on key fob.
Immobilizer should now recognize it, if it was original fob but car or fob battery was changed or is now low.

Saabs are particular about batteries that are otherwise good, but just below 12 volts.

I cant get the central locking to work on a saab 9 3 2003 model. i replaced the battery.It made no diffrence.cant find a fuse on the car for it.

Take the battery out of the key fob and stand close to the car, or sit inside, and put the new battery back in and try need to be close to the car so the security unit picks up the signal from the key fob. Good luck

I have a Saab 93 TID (2005 Vector) KEYFOB PROBLEM!

I suspect you have a problem in the security system receiver module, which in most cars must be programmed by the dealer.
