We see alot of customers who think they need a new key battery, even though the key is faulty. This is especially true with this style of car key, used on the Vauxhall Agila and Suzuki Ignis. The symptoms are that when you press one of the buttons, it does not respond as well as the other. The problem is simply the type of switch used, underneath the rubber button. It has a simple diaphram that wears out and then stops clicking. These tiny switches can be changed if you are very careful. Find a local Car key Man if you don’t feel confident.

Put the screw safe to one side and then this cover just flips off. Pop that out the way. There is a pod that sits inside the Vauxhall Agila key. And the easiest way to get that out is to just push on these buttons and take that out.

Put the key to one side. The key battery is under here, and it’s held on by two clips.

There we have the battery. You see on the battery you can’t see any writing. That’s how you know you’ve got it the right way. Just pop something underneath to get that battery out.
