Full guide for rebuilding the Saab 9-3 and Saab 9-5 Alarm Siren with battery replacement. This is the fix for the “Service Theft Alarm” or “Theft Protection Failure” warnings, and also stops random alarms from occurring.
This is part 2, check out part 1 here: https://www.youtube.com/watch?v=TLYQ8VvEZlg
Part 3 is here: https://www.youtube.com/watch?v=LQ0L_IGPEOw
Parts needed: Two Sanyo CR17335 Lithium Batteries. Do not use CR17335SE batteries, they will not work.
I purchased batteries from eBay: http://www.ebay.com/itm/322468835797
CR123A batteries can also work, but you will need to attach the solder tabs.
You need three electrolytic capacitors:
C1: 16 V, 10µF
C2: 10 V, 220µF
C4: 25 V, 330µF
While higher voltages work, make sure the capacitors don’t become too big. You need everything to fit in the siren housing.
You also need conformal coating. I used PRF 202 spray, but there are many options.

first class presentation guys. thank you
Hi there. I have a question: with the alarm out of the car, is there a way to test it ? Not by using the car's connector, but for example putting small voltage on the connector pins. The reason is that the batteries still produce 3V and few amps, so I'm not sure they need to be replaced.
Well done, Thank you for showing us.
Thank you very much! I ordered batteries from "Elfa", faster shipping than from china. But the batteries I ordered there was not the "Sanyo", it was another Japanese brand.
I have now also repaired my alarm system (i hope)… Because the previous owner (my dad) programmed the alarm system out of the car with the Tech2 I now need to reprogram it back in. This I will do when I get a hold on my brothers Tech2. Can't wait to see if this fix actually worked 😀
Love your content, please make more!
I have a 2009 9-5 Aero that the alarm horn keeps going off, but there is no siren (or pcb batteries to fail), 2006-09 have no siren as far as i know. Anybody have any ideas?
Thanks, well done and very clear – camera pics/ focus excellent – UK I used Sidmaster.co.uk based in Glos. – quick and very thorough – I am getting occasional fault reporting on the SID, but Damon [Sidmaster] tells me that other alarm components need checking and if I set the alarm to 'doors only', I have not had an alarm go off – so I am waiting for that section!!!!! + going to ask my SAAB mechanic. What I like with your presentation is the understanding I glean – keep it up! Ross
Jonathan. please continue with your vids with tips and tricks. I learn so much from you. Keep up the good work. Best Regards Johan.
Väntar med spänning på nästa video! Jag har tänkt montera larm i min 03a 9-5a… Måste fixa en hörna i garaget att löda i…
My 9-5 from time to time will say "Key Not Accepted" even after having replaced the batteries in the remote. My car is a 2000. Remote locks still work as well. I use the workaround where you press any button on the remote while cranking the car and it works. But is there a solution to properly fix the issue?
RoHS wasn't required for automotive products until recently. This board is not lead-free.
You stated that the older alarm sirens can be unscrewed but you did not state up to what year. I ask because I have to do this to my and my wife's car, both are 9-5's, 2000 aero wagon and 2001 aero sedan.
Thank you very much. I will repair my saab's alarm unit like you have done
Hi Saab pilots! These should be correct type batteries with 2+ pins and 1- pin; http://www.ebay.co.uk/itm/Saab-93-9-3-95-9-5-Twice-Alarm-Siren-Battery-Repair-Kit-2x-Sanyo-Mfd-02-17-/121587909756?hash=item1c4f34447c:g:yXQAAOSwnLdWs9Mx
Excellent presentation @Trionic Seven. Try to get the Soldering Iron off the joint a bit sooner if you can 😉 I now feel well equipped to take this job on myself. And thanks for the tip about the coating. 🙂
Bra video, mysig lekhörna!
Great videos m8 very informative . My 9 5 is a very early model , one of the first 25 off the line in 1997 . I have had problems with the alarm going off , but not for the reason you give lol. Someone in the street who visits has a Vauxhall Astra 2002 , when he arms the car alarm mine kicks off lol , then when he goes he disarms the car , mine kicks off again lol. We've stood by the cars & tested it . There was another time we went shopping & parked up by a shop with flats over it , the car alarm kicked off a few times , so i was walking back to the car when a woman walked out of the door to the flats with a remote in her hand either an alarm or a doorbell and everytime she pushed the button off went my alarm lol we stood there laughing about it for a bit then I moved the car lol & it stopped . Luckily the guy who had the Astra scrapped it & got a newer one & the problem has ceased , so i aint touching my alarm box , 🙂
Grym video! Lite feedback bara, är det inte mer korrekt att säga "positive" och "negative" istället för "plus" och "minus" i engelskan när man pratar om elektronik(?)
great job my 2007 is sealed o I am looking for older one
good content !
Jag kör inte saab långre da jag har gått över til 'fienden', VW, men jag gillar dine filmar så mycket at jag tittar på dom titt å ofta, precsis som jag gjorde forut också 🙂 Mycket bra!
Very detailed video! Great information as always. I'm considering doing another car tour for my newly acquired 9-3 Aero for the channel. Would you be interested in me doing so?
Cheers! That's what I needed. My neighbours was going to kill me, and drop my car out of the ciff.
You've just saved one saab with it's owner
Thanks 🙂
