We handle every type of lock service you might need in Marcus Hook. Residential rekeying when you move into a new home or want to change who has access. New lock installation for upgraded security or replacement of worn-out hardware.
Emergency lockout service gets you back inside fast, whether it’s your front door, back door, or even mailbox locks. We work on deadbolts, door knobs, levers, mortise locks, and electronic locks—basically any locking mechanism in your home or business.
Marcus Hook’s mix of older and newer homes means we see everything from vintage mortise locks to modern smart locks. Our experience with all types means we can maintain, repair, or upgrade whatever security system you currently have.
We typically respond to emergency lockouts in Marcus Hook within 30 minutes, depending on your exact location and current call volume. Marcus Hook is a small borough, so we can usually reach anywhere in town quickly.
When you call, we’ll give you an accurate time estimate based on where you are and what our current schedule looks like. For true emergencies—like being locked out with children in the car or during severe weather—we prioritize those calls and respond as fast as possible.
Emergency service is available 24/7, including weekends and holidays. We understand that lock problems don’t wait for business hours.
Rekeying typically costs less than replacing your locks entirely, usually ranging from $20-40 per lock cylinder. The exact price depends on the type and brand of locks you have and how many need rekeying.
We provide free estimates before starting any work, so you’ll know the cost upfront. Rekeying is often the most cost-effective option when you move into a new home, lose keys, or want to change access without replacing perfectly good lock hardware.
If your locks are old, damaged, or you want to upgrade security, we’ll discuss whether rekeying or replacement makes more sense for your situation and budget.
Yes, we service traditional mechanical locks and modern electronic locks, including smart locks and keypad entry systems. Many Marcus Hook homes have a mix of both, especially if you’ve upgraded some doors but kept original hardware on others.
For electronic locks, we handle battery replacement, reprogramming, troubleshooting connectivity issues, and mechanical repairs. We stay current with the latest smart lock technology from major brands like Schlage, Kwikset, Yale, and August.
Traditional locks remain popular and reliable—we maintain, repair, and rekey standard deadbolts, knob sets, and lever handles. Whatever type of locks you have, we have the tools and knowledge to service them properly.

Absolutely. We can create new keys even when you don’t have any originals to copy from. This involves either picking the lock and creating keys from the lock cylinder, or in some cases, replacing the lock entirely.
For car keys, we can cut and program new keys for most vehicles, including transponder keys and key fobs. This service typically takes longer than simple key duplication, but we can handle it on-site in most cases.
The process and cost depend on your specific lock type and security level. We’ll assess your situation and explain the best approach—whether that’s lock picking, cylinder replacement, or complete lock replacement—before starting any work.
