Smart Door Lock Installation For Buildings Where Keys Have Stopped Being Secure
Keys are the weakest part of most Lagos homes and offices. They get copied at the junction, lent to workmen, lost by tenants, and inherited by whoever held them before you.
Changing the lock means changing everybody’s key, so it never quite happens. The old keys stay out there, and you have no way of knowing who still holds one.
AAO Engineering Services installs smart door locks that replace keys with codes, cards and fingerprints. Every lock is original equipment with a warranty and a mechanical override. Every installation is fitted to the door you already have. Every user is set up individually — and removed in seconds when they leave.

What customers say about our work
They assessed our load before recommending anything. Final quote matched the bill we were shown — no surprises, neat wiring, and the house hasn't seen a generator since.
Mrs. A. BakareLekki Phase 1 Installed an 8-camera CCTV system with remote viewing on my phone. Clean cabling, labelled everything, and trained my family on the app before leaving.
T. OkonkwoMagodo GRA Professional from the free site visit to after-sales. They even called a week later to check the system. That's accountability you rarely see.
Engr. E. AdeyemiIkeja GRA Our shop runs on their solar setup now. Diesel costs dropped by more than half in the first two months. Original panels, proper warranty papers.
L. FernandezAjah Automatic gate + intercom done in three days, exactly as quoted. The finishing is so neat you'd think it came with the house.
B. AdewaleVGC Honest people. They told us our existing inverter was fine and only needed a battery upgrade instead of selling us a whole new system. We'll never use anyone else.
