What are your business hours for emergency locksmith services?
Emergency lockout and locksmith services are available strictly during regular business hours: Monday to Friday, 9:30 am – 6:00 pm, and Saturday 10:00 am – 4:00 pm. We do not offer 24/7 lockout response, ensuring our technicians maintain quality and reliability. If you’re locked out in Havertown, Narberth, or anywhere in Delaware or Montgomery County during these times, call our main Havertown line or Narberth number for prompt assistance. For after-hours inquiries, please leave a message and we’ll respond on the next business day.
Can I get my knives, tools, or mower blades sharpened by mail?
Yes! We offer a mail-in sharpening service for knives, scissors, and select tools. Simply package your items securely, include your contact details, and ship them to our Havertown location. Our technicians will expertly sharpen your blades, dip them in red wax for safe transport, and return them promptly. This service is popular with chefs, woodworkers, and gardeners across Delaware County and Montgomery County, especially for hard-to-find specialty sharpening. Contact us for packing tips, turnaround times, or to confirm eligibility for large items.
Do you provide key fob programming and replacement for modern vehicles?
Absolutely. Della Polla Supreme Edge LLC offers in-house programming for most transponder keys, remotes, and push-button fobs—including many makes and models commonly found in Havertown, Narberth, and surrounding areas. This means you don’t have to pay dealership prices or wait for parts to be shipped. Call ahead with your vehicle information to confirm compatibility and current pricing. Our automotive locksmithing expertise is a leading reason customers choose us for car key services in Delaware and Montgomery Counties.
What is the 90-day warranty, and what does it cover?
Every locksmith and sharpening service comes with a 90-day warranty covering parts and labor. If a part we’ve installed or a sharpening job fails due to workmanship or material defect within 90 days, simply contact our Havertown shop for a prompt resolution. This warranty exceeds most local standards and is part of our commitment as a Certified Registered Locksmith (CRL), ALOA member, and PA Registered Home Improvement Contractor. For full warranty terms or questions about specific services, our team is here to provide details.
Are there extra fees for credit card payments or discounts for cash/check?
To keep our pricing competitive in Havertown and Narberth, we apply a 4% processing fee to credit card transactions. However, this fee is waived for cash or personal check payments, giving you an instant discount. This policy helps us avoid passing hidden costs on to our community. You’ll always see transparent pricing whether you’re paying for a $4.99 key or a $400 commercial security service. For high-value transactions, choosing cash or check can provide significant savings.
What types of knives, tools, and equipment do you sharpen?
We sharpen a wide range of items, including chef knives, serrated knives, paring knives, machetes, jointer and planer blades, wood chipper knives, carbide blades, rotary lawnmower blades, reel mowers, hedge cutters, hand saws, chain saws, hair shears, tin snips, and lopping shears. Each sharpening is performed by a skilled craftsman and finished with our signature red wax dipping for safe transport. If you have a specialty item or need bulk sharpening, contact us to confirm pricing and turnaround.

Our primary service areas are Havertown, Narberth, and the broader Delaware County and Montgomery County regions. We regularly serve neighborhoods like Ardmore, Broomall, Upper Darby, Wynnewood, and Bala Cynwyd. For sharpening, our mail-in service allows us to support customers even beyond these local areas.
