Recently the car started to complain that the battery in the keyfob was "low", so it was time to find out how the car and keyfob work together.
Our 2015 Outlander has "keyless" operation, meaning you don't have to insert the key into a lock to operate the car. However if the battery in the keyfob does go completely flat then the car can still be used, via the physical key stored in the keyfob.
Flip the keyfob over onto the side with the Mitsubishi logo.
Slide the releasing mechanism, just above the logo, and slide the key out of the keyfob.
You can use the physical key to unlock the driver's door, then put the key back into the keyfob, and place the keyfob into the slot in the central console, just to the right of the cigarette lighter socket. You can then operate the car as per normal. I'm going to infer that the slot has an RFID reader built into it, and the keyfob has a passive RFID tag, with the code required for the car's immobiliser to allow the car to be used.
Keyless operation is far more convenient, and changing the battery in the keyfob is very quick. At the end of the keyfob where the physical key is located there is a notch in the plastic. Using a screwdriver you can pop the two halves of the keyfob case apart.
The top case of the keyfob, with the buttons, has a CR2032 "coin cell" battery in a holder. The C of CR2032 indicates that the battery is 3V lithium, the R indicates that it is round, 20 is the diameter in millimetres, and 32 indicates a thickness of 3.2mm.
If you can't get hold of a CR2032 you can substitute a BR2032 battery instead. BR2032 are also 3V lithium batteries, but use a different material for the positive electrode. CR2032 are better at delivering the short bursts of current needed for keyfob operation than the BR2032, whereas BR2032 batteries are better for supplying a constant current, as you might find in the real-time clock of a computer. However in a pinch a BR2032 will work in a keyfob.
The old battery can be lifted out.
And a new battery fitted with the positive side, indicated by a "+", upwards. Try to not touch both the positive and negative sides of the new battery while you're fitting it, as you'll discharge the new battery if you do.
Simply snap the two halves of the case back together, slide the key back into the keyfob, and you're good to go for another few years.
