Cost to Duplicate House Keys
Duplicating a house key means matching an original key on a compatible blank, either through a cutting service or by manually making an impression and cutting the blank. Homeowners often need an extra key when an existing one is worn or damaged, but manual work requires a sound original, the right blank profile, and careful cutting.
Common reasons homeowners do this job
- Adding an extra house key
- Replacing a worn original key
- Replacing a damaged original key
- Replacing a duplicate that works unreliably
DIY or call a pro?
A professional key-cutting service is worth considering if identifying a compatible blank profile, clamping the keys in a vice, or cutting metal to match the pattern feels uncomfortable. For manual duplication, use caution around the lighter's open flame and wear eye protection while cutting metal because debris can fly. Test the finished key before relying on it, since a manually made duplicate may work unreliably or could get stuck in the lock.
Frequently asked questions
- Can I duplicate a house key myself, or is a cutting service better?
- Manual duplication is a legitimate DIY option when the original key is in good condition and a compatible blank is available. A cutting service is worth considering if the blank profile is uncertain or the metal-cutting steps are uncomfortable. A hand-made duplicate should be tested in the lock because it may function unreliably or may get stuck.
- What makes the price of duplicating house keys go up?
- The price can rise with the number of keys, labor time, materials, and any minimum or trip charge for a small job.
- What should I check before copying a house key by hand?
- Inspect the original first to make sure it is in good, undamaged condition, then identify a key blank profile that matches it. Starting with a poor original or the wrong blank makes it harder to create a usable duplicate.
- Why can a manually duplicated key get stuck in the lock?
- Manual key duplication can produce a key that functions unreliably or can get stuck in the lock. Secure the original and blank in a vice while cutting, and test the new key in the lock after matching the pattern.
