How long does the battery usually last in the keyfob?

I bought the car in May 2010 and put fresh batteries in the fob.

Last couple of days the key isn't recognised and then eventually works after several tries. Is four months about right for the life of the batteries?

The car gets used every day.

Thanks

They normally last a couple of years but it all depends on useage.
 
ive got a genuine metal dealer keyfob that sometimes effects the key being recognised
 
c220 2001 central locking key fob
i have just replaced the radio amp as radio and remote locking didnt work. radio still doesnt work although replaced with exactly same amp as before. i can live with this but can anyone talk me through programming amp to receive keyfob signal from original key... i need help to pair these 2 componenents !!!!

can u help c55??
 
They are plug and play and no programming required. I suspect you need a new key if the CL does not work
