2023 lost one of the two keys to Kryptonite Kryptolock and to the Abus padlock:
- rebuying cryptonite, seems exactly the same. If the old key is ever found, it can re-enter usage.
- replacing Abus padlock buying a similarly featured Master lock "commercial" padlock, looks like this one: www.screwfix.com/p/master-lock-excell-laminated-steel-master-keyed-weatherproof-padlock-51mm/153KH

Went next to a tower and then got signal. So the receiver is much worse than the pixel one. Vibration appears to be broken.
