Your car key fob stops working and suddenly you’re stuck outside your Darby home or in a Lansdowne parking lot. Can’t get in, can’t start the engine, can’t get to work or pick up the kids.
We fix that problem fast. Most key fob replacements and programming jobs are done while you wait – usually 20 to 30 minutes. No appointments needed, no leaving your car overnight at some service department, no dealing with dealerships that treat you like a number.
You get a replacement fob that works exactly like your original, programmed correctly the first time, at 25-40% less than what the dealership charges. Then you drive away and get on with your day.

Call us and tell us what’s happening with your key fob – whether it’s completely dead, buttons aren’t working, or you lost it entirely. We’ll ask about your car’s make, model, and year to make sure we bring the right equipment to your Darby location.
Our mobile technician arrives with a fully equipped van. We verify your ownership, then either repair your existing fob or program a brand-new replacement. The whole process typically takes 20-30 minutes, whether you’re at home, at work, or stuck in a shopping center.
Once your new key fob is programmed and tested, you’ll have full functionality – locking, unlocking, trunk access, panic button, everything. We test every function before we leave, so you won’t have any surprises when you try to use it later.
