Replacing a Traditional Lock with a Smart Lock: Steps and Cost

Replacing a traditional lock with a smart lock is one of the most common requests from homeowners in Riyadh, Jeddah and Dammam — especially for those who want to ditch the metal key for good. The good news: swapping a smart lock in place of your current one is simpler than you think, and in most cases you won't need to change the door. This Fixlr guide covers the full steps, how to know a lock fits your door, real costs in Saudi Arabia, and when to call a verified technician. ## Do you need to change the door? In the vast majority of cases, no. Most smart locks are designed to replace a traditional lock using the same or similar cut-outs and dimensions. Minor door adjustment is only needed when the new lock differs significantly from the old one, or on thin-frame aluminium doors — see getfixlr.com/blog/smart-lock-aluminum-door. ## Know your current lock first - **Mortise lock** — the most common type on wooden and steel doors in Saudi Arabia, fitted inside a pocket in the door edge. Learn more: en.wikipedia.org/wiki/Mortise_lock. For a smart mortise replacement, see getfixlr.com/services/guardian-mortise-lock. - **Rim lock** — surface-mounted on the inside of the door. Its smart equivalent: getfixlr.com/services/safeguard-rim-lock. For more on types, see getfixlr.com/blog/types-of-smart-locks. ## Step-by-step replacement 1. Assess the door and current lock (material, thickness, lock type). 2. Take measurements — backset, bolt length, pocket dimensions, door thickness. 3. Choose a smart lock that matches those dimensions and your preferred unlock methods. 4. Remove the old lock carefully without damaging the door. 5. Install the smart lock — outer and inner units, bolt and motor, then align. 6. Program and test — fit batteries, enrol the first admin/user, and test repeatedly. ## How much does it cost in Saudi Arabia? Cost has two parts: the smart lock itself (varies by brand and spec) and installation/programming. Installation typically runs SAR 150–200 depending on city and lock type.

With Fixlr the price is transparent and known before you book. ## When the door needs adjustment - The existing pocket is smaller than the new lock and needs slight widening. - Aluminium doors may need a dedicated lock or an adapter plate. - Switching between a rim and a mortise lock. A verified technician assesses this on-site first. To prepare, see getfixlr.com/blog/how-to-prepare-your-home-for-smart-lock-installation. ## DIY or a verified technician? If you're handy and your lock is the easy type, you can do it yourself following the manufacturer's instructions. Brands like Yale publish detailed guides (yalehome.com). But a verified technician ensures correct measurements, proper alignment, safe programming, and no damage to the door. ## Tips before you replace - Keep your old lock or an emergency key until the smart lock is confirmed working. - Confirm compatibility with your door type before buying. - Choose a lock with multiple unlock methods. - Ask about warranty on both the device and the installation. ## FAQ **Will I have to change the door?** Usually no — replacing the lock is enough; adjustment is only needed for big lock-type differences or aluminium doors. **How long does it take?** Typically 30–60 minutes per lock, including programming and testing. **Can I still use a key?** Most smart locks include an emergency key cylinder. **What about the old lock?** Keep it as a backup or reuse it on an interior door. ## Book a Fixlr technician Fixlr connects you with a verified, rated technician who assesses your door and replaces your traditional lock with a smart one — same day, at a known price, with a service warranty in Riyadh, Jeddah and Dammam.
