That’ll teach me not to put my keys on top of the car when getting things ready. I drove off and next thing I knew, they slid off onto a busy roundabout! Managed to retrieve them but one or two bent and my fob unresponsive! Dangerous as well with bits of mangled sharp metal sticking out! Well now I’ve finally undone the key ring with pliers and flattened problem keys in a vice. And just realised fob still works, just need to press a bit harder!
