Lock Repair FAQs

Common questions about our Lock Repair services

Lock repair typically costs $75-200 depending on the problem, which is much less than lock replacement at $250-500 or more. Simple issues like adjusting strike plates or lubricating mechanisms cost less, while complex repairs involving internal components cost more but still save money versus replacement. We provide upfront pricing before starting work, and our rates are significantly lower than dealerships for automotive locks. Most repairs can be completed during one service visit, saving you time and additional trip charges that other locksmith services charge.
We repair both traditional mechanical locks and modern electronic locksmith systems throughout Delaware County and Philadelphia County. Our technicians stay current with smart lock technology including keypad systems, electronic deadbolts, and commercial access control devices. Many electronic lock problems involve programming issues, dead batteries, or connectivity problems rather than mechanical failure. We diagnose the actual issue and often resolve electronic problems quickly without replacing expensive components. For complex systems, we follow manufacturer specifications to maintain warranty coverage while restoring proper function.
We typically respond to emergency locksmith requests within 30-60 minutes in Delaware County and surrounding Philadelphia County areas. For true emergencies like security breaches or complete lockouts, we prioritize these requests and often arrive faster. Our mobile service trucks carry extensive repair parts and tools, allowing us to fix most problems immediately without return trips. Even during busy periods, we understand that broken locks create security vulnerabilities that can’t wait. We’ve been providing emergency locksmith service to this area for over 100 years and know how to respond quickly when you need us most.
Most lock problems are actually repairable with the right expertise and parts. We regularly fix sticking mechanisms, hard-to-turn keys, loose hardware, broken springs, worn pins, and even keys broken off inside locks. Door alignment issues, damaged finishes, and internal wear can often be repaired cost-effectively. However, locks with cracked housings, severely damaged cylinders, or obsolete mechanisms without available parts may require replacement. Our experience with locks dating back decades means we can often repair systems that other locksmith services consider beyond fixing. We’ll always give you honest assessment of repair versus replacement costs.
Yes, we provide a comprehensive warranty on all lock repair work including both labor and any parts we install. The warranty period varies based on the type of repair but covers our workmanship completely. If a repair fails due to our work within the warranty period, we return to fix it at no charge. We use quality replacement parts and proper repair procedures developed over five generations in the locksmith business. Our reputation in Delaware County has been built on doing repairs right the first time, and our warranty demonstrates confidence in our professional locksmith services.
Absolutely – we repair locks even without original keys all the time. Our technicians can work on lock mechanisms directly, and we can rekey the lock during repair to work with new keys. This situation is common since many lock problems happen when people lose keys and force the lock, causing internal damage. We assess the damage, repair the mechanism, and provide new keys that work perfectly. In many cases, we can even create new keys to match existing locks if the cylinder isn’t damaged. This saves you from replacing all your locks when only one needs repair and rekeying.
