Can I receive deductions to my deposit for not returning keys?

Yes, if any keys are not returned at the end of your tenancy this could mean that there are deductions from your deposit.

Copied keys or unreturned keys can cost around £10 to £15 to replace. If multiple keys are not returned, it may be more appropriate to replace the lock entirely. Depending on the system, replacing locks can cost between £20.00 to £80.00.
