Seeking Advice on 2010 Volvo V70's Alarm System and Weak Ignition Issues

Hey, I feel you, faced something similar with my 2007 Volvo S60 not long ago. The alarm was a pain, constantly blaring for no rhyme or reason, plus the ignition was on and off too, just like you've mentioned. Turns out, it was the alarm system just as I'd suspected - ended up being a problem with the optical locking mechanism within the system. The mechanic had to redo the entire coding to rectify the issue with the optical locking. To be honest, it wasn't a quick pit stop. Took a fair bit of time for them to crack it. Regarding the weak ignition, it was just an aging battery. Swapped it for a new one, and voilà, worked like a charm! Nothing to be overly stressed about but it's definitely not to be ignored. So yeah, I'd suggest getting your alarm system and battery checked out by a trusty mechanic. Good luck!

Hey, thanks for sharing your experience, really helpful to hear! The optical locking system issue sounds like a tricky one, but I'm sure glad they got yours sorted out. I wanted to ask - do you recall how much exactly it cost you to fix these issues? And apart from what you've mentioned, have you noticed anything else acting out of order in your Volvo since it got fixed? Cheers!

Hey, no problem at all, glad to help a fellow Volvo driver out! Don't remember the exact costs for everything, but getting that pesky alarm system back in shape cost about 45 €. And let me tell you, it was worth every cent. No more blaring at all hours, and the optical locking is crisp as ever. As for anything else behaving oddly since the repair... nah, not really. She's been running smoother than ever, honestly. Feel like my trusty ol' Volvo got a bit of a revitalisation after seeing the mechanic. The ignition issues are all sorted thanks to the battery replacing and I haven’t noticed anything else amiss. Just make sure your mechanic does a good job and it'll end up like a brand new ride! So don't stress out. It'll all work out, just like it did for me. Cheers!
