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.
In apartment towers there is a second gatekeeper: building management. Entrance doors in towers are usually fire-rated, and some managements prohibit any modification to them, full stop. Retrofit smart locks that clamp over the existing thumb-turn on the inside of the door — no drilling, no cylinder change — exist precisely for this situation, and a good installer will steer tenants toward them. Fitting one is quick work, typically at the lower end of the AED 200–450 install-only band.
