hello, does anyone know which battery model i need and where i can get it replaced. Thanks
Edited I ment for the key alarm

if you are looking for something nice, go for the Optima red top 34R. you can replace it yourself very very easily.

yeah u are going to need a 27F battery is alot bigger then the sc300

What size battery would I need for an sc300

I run a 27F battery in my SC300 and it fits in the tray.

haha sorry guys I ment the battery for my key alarm.

I have a Red Optima. Its MUCH better than stock or any other average, and its a bit smaller. The OEM bracket still holds it in place though.

I just read your latest...you can try and fit the Optima in your key fob, but it might be a bit heavy.

if you already have a battery in your key fob, just take it out and you will see the battery size indicator imprinted on it. i believe it is CR1216 or something like that. it is a 3v battery you can find at any pharmacy or shopping center.

Just playing...While your digging around in your key fob, you should look up (Search) the thread about extending the signal range of your Fob...I did it and I can unlock my car from the other side of our 30,000sq ft. building.

Ok, I enter "Fob*" ; "fob range" range extender" into the search funtion and come up with nothing. Where exactly is this thread?

Where can I find this thread regarding "extended signal strength" Thank you for your time.

Hi, I have a 95 Lexus SC400. I need to know what size battery to purchase as soon as possible. Also does it matter what side the positive and negative posts are on or just the size?

Thanks
