Need to change my bleeper batteries, 2off CR2025 - got the batteries, got the keyfob, got the 'tool' which unscrews the back ......................

Only IT DOESN'T!!!

The indents have worn down after all these years and now the tool will not grip to open the back

Anyone solved this? It is a SIGMA Alarm I understand (MY00) ........

I am looking at an adjustable wrench right now - any reason why I shouldn't??

 

try hitting it off your knock link lol lol

 

Just turn it.... Thats what i did with mine.

 

The adjustable wrench won in the end Job done .....

 

Yep, old pair of pliers always does it for me, Pete.

 

Don't tell us that's the first set of batteries it's had in 7 years..!

Were the batteries made by the same co as your brake pads..?

 

Yes, second set in 7 1/2 years ..... didn't really need them replacing but I had to be right next to the car to open it - new batteries now let me open it from my bed

I've never heard of Sigma Brake Pads?
