Frequently Asked Questions About Key Duplication Services in Connecticut


How long does key duplication take?

Most standard key duplication is completed in just a few minutes while you wait. More complex keys or specialty blanks may require additional time, but we strive to provide fast, efficient service for all customers. During busy periods, there may be a short wait, but we work diligently to serve everyone promptly.

What do I need to bring to get a key duplicated?


Simply bring the original key you want duplicated. For high-security or restricted keys, you may need to provide identification or proof of authorization. Our staff will let you know if any additional documentation is required. 


Do you duplicate car keys with chips or transponders?

We can duplicate the physical cut of most automotive keys, including those with transponder chips. Programming transponder keys (keys with chips in them) varies by vehicle make, model, and year. We recommend calling ahead to discuss your specific vehicle's requirements so we can let you know what services we can provide.
