The 24 Hour Car Unlocking Advantage

If you’re stranded on a major highway such as I-10, I-35, Loop 1604, or US-281, you may also be able to flag down a TXDOT HERO unit, which provides free roadside assistance when available.
Outside of those options, most drivers will need to rely on local mobile mechanics, towing companies, or roadside service providers such as 24 Hr Car Unlocking that offer jump-start services for $55-$75.

Understanding Car Battery Failure in San Antonio
One of the most common reasons people experience car battery failure is from leaving headlights or interior car lights on overnight. This will drain your vehicle’s battery within hours of the light being left on, along with any other accessory using unnecessary power. Also, while many people assume cold weather takes the biggest toll on car batteries, the extreme heat of San Antonio places immense strain on car battery systems and increases the likelihood of frequent battery failure.
Taking the time to ensure all components of your vehicle are shut off when you leave your car, along with avoiding prolonged exposure to extreme temperatures, can prevent you from breaking down and needing frequent battery replacements.

Hear From Our Customers
Eli did a great job! My car was in alarm mode so you cannot unlock the doors from the inside. It was quite a task but he eventually got me in and he didn't charge me more for this! He was a very kind and smart young man and I appreciate his help. The price was lower than every other place I called. Thank you! 🙏

Very professional and had my car unlocked and handed me my keys within minutes. He was very respectful of my car with no damage to the vehicle. I would not hesitate to refer this company to anyone. Great job guys!
