In Ohio, there is no state law that sets a specific recommended charge for a lost or replacement key. The cost of a replacement key may vary depending on the type of key, the complexity of the lock, and the locksmith or service provider you choose to work with.
It is best to contact local locksmiths or service providers in your area to get an idea of their pricing for replacement keys. They may be able to provide you with an estimate over the phone or in person after evaluating the lock and key.
Regarding emergency locksmith services in Ohio, the cost may also vary depending on the provider and the specific service needed. It is best to research and compare rates from different providers to ensure you are getting a fair price. Some locksmiths may also charge extra fees for emergency or after-hours services, so it is important to clarify the fees upfront before agreeing to any services.
