How long does it actually take to install a smart lock?

In our 35 installations, the average time was 47 minutes for the simplest cases and over 2 hours for the most complicated ones. The marketing claims of '15-minute installation' are only true for ideal conditions with standard, well-maintained doors. Real homes with older or non-standard doors take significantly longer.

How much does professional smart lock installation cost?

In our test group, professional installation was required in 8 of 35 cases and cost $150–$350 per lock depending on the complexity and location. Some homes with very old or unusual hardware required more expensive custom work. Budget $200–$400 if you think you might need professional help.

What parts or tools might I need that are not in the box?

Common items we needed across our 35 installations included replacement strike plates ($10–$25), longer screws ($5–$10), shims for doors that were not square ($5–$15), and occasionally a new deadbolt if the existing one was too worn to work with the smart lock ($20–$40). Budget an extra $20–$80 for parts and tools.

What are the most common problems that cause installation to fail?

Non-standard deadbolts, worn strike plates, doors that are not perfectly square or have settled, and frames that are too narrow or too wide for the smart lock's requirements. These issues affected 40% of the pre-1990 doors we tested and often required modifications or professional help.

Should I buy a smart lock if I am not sure I can install it myself?

Only if you are prepared for the possibility of professional installation ($150–$400) or modifications that may cost additional time and money. Before you buy, open your current lock, take photos of the deadbolt, strike plate, and door frame, and assess whether your door is likely to require modifications or professional help. The convenience is real, but only if the installation actually works on your specific door.
