I have been storing my spare key fobs with the batteries installed. Once a year I test the key fobs to ensure they are still operational. I've been doing this for the past 10 years and so far so good, I've never needed to replace the batteries. Now that replacement key fobs have quadrupled in price to $1000+ CDN, I'm thinking I should store the fobs with the batteries removed to eliminate the risk of the batteries leaking and damaging the fob. I understand this will require a re-programming of the fob to re-enable the lock/unlock function. I'd be interested to know if anyone has experienced leaky key fob batteries?

 

 

 

Or just replace the batteries every five years?

 

I just use the FOB's, I have both with me when traveling.
