Losing Your House Keys: A Guide to Rekeying and Replacement
If house keys are missing, first establish whether you can enter safely using an authorized spare. Regaining entry and changing access are separate tasks: rekeying can stop an old key operating a compatible cylinder, while replacement may be appropriate for damaged or unsuitable hardware. This guide compares the options and what to ask before booking.
Discuss the affected doors and your location at (720) 248-8087 or request a locksmith estimate. Have identification and proof of authorization ready.
Choosing a Rekey Locksmith
Ask for the proposed work and an itemized estimate covering the visit, affected cylinders, keys, labor and any replacement parts. If inspection is needed, confirm what may change the price and ask for approval before additional work. The price of small internal parts alone does not represent the entire service.
Your Options When Rekeying House Door Locks
Professional Locksmith vs. DIY
Compare a mobile visit with taking suitable hardware to a provider or doing work you are equipped to handle. Disassembling or rekeying a cylinder requires appropriate tools and knowledge. Review the current service warranty and policy rather than assuming unlimited coverage.
DIY: A Cost-Saving Method
DIY replacement may be suitable when the new hardware matches the door and you can follow its instructions. Locks can share a key only when the keyways and keying arrangement are compatible. Electronic setup is separate from mechanical installation. If a lost key could identify the home, discuss the affected access points rather than only replacing the missing copy.
Front Door Lock Change Cost
Request an estimate for the hardware and installation you need. Compare the exact product, installation and call charge. Schlage and Kwikset offer multiple styles and finishes, but confirm current fit, package contents and availability.
