When I bought my bike a few years ago I fitted these 'security' wheel clamps: https://www.decathlon.co.uk/p/seat-post-and-wheel-security-bike-clamps/_/R-p-170559
I've now managed to lose the pentagonal key that came with them. Decathlon don't sell the keys separately - they said I'll need to buy a new set, which aggrieves me as it's only the key I need.
There are other companies that make pentagonal keys, for example this: https://winstanleysbikes.co.uk/whyte-security-key.
Does anyone know if they're likely to work, or do different companies use slightly different specifications?
