Property Key Register

Property Key Register is an offline app (one HTML file in a zip) for an agency or property manager who hands keys to viewers, contractors, cleaners, tenants and owners. Each key set belongs to a unit and records how many keys it has. Every handover records who took how many keys, why, and the date they are due back. The app refuses to give out more keys than the safe holds, shows the keys that are overdue or came back short, prints a key receipt to sign, and compares each safe count with the number the log says should be in the safe.

The problem it removes: Keys leave the office with a viewer, a plumber or a tenant and nobody writes down who has them. When a contractor does not return a key, or a tenant moves out with the parking remote, the office finds out months later. This app keeps a simple log of every key that leaves and returns, so you can say who holds which keys today.

What is inside:

• Today page: keys out now, handovers overdue or due today, keys that came back short, long-term keys held after a unit became vacant and key sets whose count is due
• Key sets per unit with tag, kind, number of keys, where it is stored, and the keys in the safe
• Handover log with holder, phone, purpose, keys given, due date, ID seen, signed, return date and keys returned
• Rules that stop giving out more keys than the safe holds, giving out a lost or retired set, and a return before the handover
• Safe count log that compares the keys you counted with the keys the log says should be there on that date
• Printable key receipt for each handover and a printable key card for each unit
• WhatsApp reminder for overdue keys, opened with the message ready to send
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: property management offices, letting agencies, building managers and small developers who hold keys for units they do not live in.

What it is NOT: It does not control access, open doors, or replace a key cabinet with locks. It does not store copies of identity documents: it only records that ID was seen. The receipt wording is a simple example, not legal advice. Fictional example data only. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (158 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1428 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
