When you're facing a security concern at your Trenton, NJ property, one of the most common questions homeowners and business owners ask is whether they should rekey their existing locks or replace them entirely. This decision can significantly impact both your security and your budget. As a trusted local locksmith company serving Trenton and surrounding areas including Burlington and Bucks County, we've helped thousands of customers make this important choice. Understanding the differences between rekeying and replacement will help you make the best decision for your specific situation.
Understanding the Difference Between Rekeying and Lock Replacement
Rekeying is a service where a professional locksmith changes the internal pins and springs inside your existing lock cylinder so that your old key no longer works. After rekeying, you'll receive new keys that operate the lock, while the original hardware stays in place. This process is typically more affordable than full replacement and can be completed quickly by an experienced locksmith.
Lock replacement involves removing your entire lock system and installing a completely new one. This option is necessary when your locks are damaged, outdated, or incompatible with your security needs. While the cost is generally higher than rekeying, replacement allows you to upgrade to better technology or change the type of lock entirely.
When Rekeying Makes the Best Sense
Rekeying is often the most cost-effective solution for residential and commercial properties in Trenton, NJ when your locks are still in good condition. Here are situations where rekeying is your best option:
- Moving into a new house or commercial space: You don't know who might have copies of the original keys from previous owners or tenants
- Lost or stolen keys: When keys go missing, rekeying provides peace of mind without the expense of full replacement
- Employee turnover: For commercial properties, rekeying is essential when staff members with key access leave your company
- After a lockout: If you've experienced an emergency lockout situation, rekeying ensures enhanced security
- Matching keys across multiple locks: A mobile locksmith can rekey all your Schlage, Kwikset, or other brand locks to work with a single key
When Lock Replacement Is Necessary
While rekeying is cost-effective, there are circumstances where full lock replacement is the better investment for your Trenton property:
- Damaged or worn locks: If your deadbolt or other lock mechanisms are damaged from a break-in attempt or years of use, replacement is necessary
- Upgrading security: When you want to install smart lock technology or higher-grade security systems
- Incompatible lock types: If you're standardizing your residential or commercial property with specific brands or styles
- After a break-in: When locks have been compromised, replacement ensures maximum safe security
- Outdated traditional locks: Older locks on State Street, Warren Avenue, or other Trenton neighborhoods may need replacement to meet modern security standards
Cost Comparison: What to Expect in Trenton, NJ
Understanding the cost difference between rekeying and replacement helps you make an informed decision. Generally speaking, rekeying is significantly more affordable, typically costing a fraction of what you'd pay for complete lock replacement.
Rekeying costs in Trenton, NJ usually include:
- Service call fee for our mobile locksmith
- Labor for each lock cylinder
- New key duplication (usually multiple keys included)
- New lock hardware (range varies by brand and type)
