Jump Start Service

A dead car battery can throw your whole day off, especially when it happens unexpectedly. Whether you're late to work or stuck in a parking lot in Katy, TX, our local mobile locksmith team offers fast and affordable jump start and battery replacement services. We respond quickly, arrive equipped, and get your vehicle powered up in no time. We also replace dead batteries on the spot when a jump isn’t enough.

Common Reasons Car Batteries Fail

Texas heat, old batteries, and forgotten headlights are just a few reasons why your car might not start. Most batteries last 3–5 years, but extreme weather and poor maintenance shorten that life. Faulty alternators or parasitic drains can also leave you stuck.

Signs You Need a Jump Start

If your engine cranks slowly, your lights flicker, or you hear a clicking sound when turning the key, your battery might need a jump. This is especially true if your car has been sitting idle or your dome light was left on overnight.

When a Jump Start Isn’t Enough

Jump starts work only if the battery still holds some charge. If the battery is swollen, leaking, or won’t hold power, it likely needs to be replaced. Our techs can diagnose the issue and provide battery replacement on the spot.
