Fast car lockout help.

Your car won't start and you're stuck in a Houston parking lot, driveway, or roadside shoulder. Whether it's a dead battery or a simple drain from leaving the lights on, you don’t have to panic. Our mobile jump start and battery replacement service is available 7 days a week, with fast arrival and affordable rates across the Houston metro area.

Common Reasons Car Batteries Fail

Extreme heat in Houston can cause your battery to deteriorate faster than in cooler climates. Common culprits include leaving headlights on, corroded terminals, old age, or parasitic drain. Knowing why it failed helps prevent future lockouts or dead starts. Read these fuel-saving tips while you're at it.

Signs You Need a Jump Start

If your car won't crank, the lights dim when you turn the key, or you hear clicking under the hood, chances are you just need a jump. A quick diagnostic by our mobile team will confirm it. We also offer tips to avoid this in the future.

When a Jump Start Isn’t Enough

If your battery won’t hold a charge even after jumping, or if it’s more than three years old, replacement may be necessary. Our techs come equipped to replace it on the spot with no towing needed. Learn more in this guide.
