How do you change the battery in mazda 5 key?
open the lid and change it.
The fob has a pry slot and prys apart.
Your Lexus dealer (Parts Dept) will change it for you for the price of the battery, I just paid $4.33 (Sept. 2008). If you want to do it yourself, purchase a CR2032 3v battery (flat disc) from somewhere like Radio Shack or Fry's Electronics. To open the key fob, hold the fob key-ring side up, and do these two things at the same time: 1) slide back the top compartment (with arrow) 2) lift that same top compartment while it's pulled back Once the top is removed, use your fingernail to pull out the battery holder, then slide the battery out of that & replace.
you get 3 mins to change the battery.
