Mitsubishi Key Fob Battery Dead, Spare Key or Keys Locked in the Car?

Mitsubishi cars in Singapore

Mitsubishi's Attrage, Outlander and Xpander are practical favourites in Singapore, including with private-hire drivers. We work on Mitsubishi models including the Attrage, Outlander, Xpander, ASX and Lancer.

A typical Mitsubishi call

This is the kind of Mitsubishi call we often get: A small company runs several Attrage cars, each with only one key. One key going missing has already cost them a day. They ask us to clone a spare for each car.

What's different about Mitsubishi keys

Mitsubishi's Keyless Operation System is found on many models, while simpler models such as the Attrage often use a remote with a metal blade. For fleets, one spare per car avoids downtime. Mitsubishis use remote keys with a metal blade on many models and keyless operation keys with push-button start on others.

Mitsubishi key fob battery dead? How to get in and start

1. Get in: Pull out the emergency key from the keyless operation key, or use the blade on a remote key, to unlock the driver's door.
2. Start the car: On many push-button models, touch the start button with the key, or insert it into the key slot if your model has one. Your manual shows which applies.

Details vary by year, so check your manual. Still stuck? Call us. Key locked inside instead? See keys locked in the car.

Mitsubishi key fob battery replacement

Most Mitsubishi fobs take a 3V coin cell (often CR2032 or CR2025): copy the type printed on the old one and fit the new cell the same way up. Not working after the swap? See key fob not working after a battery change; if the backup start above works, the Mitsubishi fob itself is fine.

Mitsubishi spare key

Down to one Mitsubishi key? We clone Mitsubishi remote key fobs from a working key, after checking your NRIC against the log card. We don't clone smart (keyless) keys. Cloning costs S$100–S$1,000 depending on the car, so WhatsApp 9224 9224 the model, year and a key photo to confirm first.

Mitsubishi key battery

The smart key for the third-generation Outlander (2014 to 2021) takes a CR2032, as do many other Mitsubishi keyless operation keys, but some older Mitsubishi remotes use a smaller CR1620. Check the old cell before you buy. On keyless models, slide out the emergency key first: the slot it leaves is where you ease the case open.

A Mitsubishi key that only works when you're standing right next to the car almost always has a weak cell. Change it then, before the car stops recognising it.

Fleets and private-hire Mitsubishis

Attrage and Xpander cars are often run by small companies and private-hire drivers, where one lost key means a day off the road. Keep one spare per car, label it by plate number (never by address), and keep the spares at the office rather than inside the cars.

Tips for Mitsubishi owners

• A spare key avoids downtime if you drive for a living.
• Replace the fob battery when the remote range starts to drop.
• Keep the spare key at home rather than in the car.
