"That mark was already there" ends here.
Every damage dispute in car hire comes down to one question: what did the car look like when the keys moved? If your answer is a tick-box diagram and memory, you lose. If it is timestamped photographs from both ends of the hire, there is nothing left to argue about.
Photos at both ends. Timestamped in between.
Deliberately the renter, not you: it is their chance to check the car before driving off, it protects them from being blamed for existing damage, and it means the handover set is one neither side can later call one-sided.
The return check is yours: walk the car, photograph it, and the return set lands next to the handover set, side by side, both timestamped. New damage has nowhere to hide and nothing to be argued into.
KeyProof never judges damage. It puts the before and after in front of you, and the call stays yours: release the deposit on a clean return, or hold it with the proof already in hand.
Condition photos sit alongside the verified identity, the DVLA licence result, the e-signed agreement and the deposit record: one exportable pack per hire, ready for an insurer on the day something goes wrong.
Camera rolls lose disputes. Records win them.
Most operators already take photos. The problem is where they live: scattered across a camera roll, undated in any provable way, mixed in with everything else, and impossible to tie to a specific hire and a specific renter months later. A condition record only has value if it is bound to the booking, the identity and the agreement, which is exactly what KeyProof does. The product is pre-launch, built with a founding cohort of UK hire firms: see the full flow in the demo or read how it works.
Every handover documented.
Every dispute shorter.
Founding spots are open to a handful of UK hire firms: locked pricing for life, and a direct hand in shaping the product.
