Replace the battery. If the button cell battery in the key fob of Aygo is replaced incorrectly or a battery is unsuitable, it can damage the vehicle key. Only replace drained batteries with new batteries in the same voltage, size, and specification. Make sure the battery is facing in the right direction when inserting it.
One of the most common problems with Aygos, aside from leaking, is the clutch. Most people replaced early ones with the 190mm unit from the Yaris, before Toyota made the switch themselves to the 190mm unit after the first face lift, which was 2009. 26 May 2014 at 10:26. #10.
