Smart locks in rentals: consent first, hardware second
The majority of UAE residents rent, and a smart lock is a modification to a door the landlord owns. Get written consent — an email or a message thread is enough in practice — before anyone drills. Most landlords say yes when you commit to two things: the original lock and cylinder will be kept safely and refitted at handover, and any holes from a different mounting footprint will be made good. Skipping this step risks a deduction from your security deposit that can exceed the entire cost of the install.
Reversibility has a price worth paying. A tenant choosing between a AED 250–400 retrofit unit and a AED 700–1,000 full replacement lock should weigh not just today's cost but the exit cost: the retrofit comes off in ten minutes when you move; the replacement means a refit visit, possible touch-up work, and a device that may not suit your next door at all.
