mpm235 14 Posted January 25 Share Posted January 25 My Gen 2 Prius had a glitch today. When I went to open it this morning, it took 4 or 5 clicks on the remote button to open the doors. Thought it might be Battery in the remote, so tried the spare remote, but it was the same, so not the remote's Battery. Once inside, Prius started fine, (the "READY" indicator flashed once). After a long run on motorway, the doors opened on first click of remote button, as usual. I'm now thinking that my 12 volt Battery is on the way out? Could this be it? Or something else? Thanks for any advice / replies, Mark. Quote Link to post Share on other sites
TonyHSD 767 Posted January 25 Share Posted January 25 Very likely 12v Battery issue. Just keep in ready mode at least twice a week for 30-40min each time if not able to drive the car during lockdown. 1 Quote Link to post Share on other sites
flash22 655 Posted January 25 Share Posted January 25 It's an ice-cold Monday morning, i bet you didn't want to get up and go out either lol 2008 on its original Battery ? 7-10 years maybe 12 years at a push, is about right for an AGM Battery 1 Quote Link to post Share on other sites
john p williams 76 Posted January 25 Share Posted January 25 I`d say ice in the locking mechanism. 1 Quote Link to post Share on other sites

I've actually been driving the car (working) all through lockdown, but she has done a few short trips the last two weeks, whilst I've been on leave). I'm now booked in at Burrows Toyota Doncaster, 08:30 in the morning, they are putting a new 12 volt in whilst I wait. Sorted! 1 Quote Link to post Share on other sites

Ice remains cold for a long time in places not in direct sunlight. Quote Link to post Share on other sites

I've done a check on the 12 volt, it is 11.8 going down to 11.2, so I definitely want a new one. Found this checking method on Youtube, this is how I checked it: 1 Quote Link to post Share on other sites
