M1 Two-door Lock Kit (Side + Rear Cargo Doors)

Thunderbolt locks are fantastic!

They sent exactly what I needed in the box and you need to tell them what you want because there’s a lot of variations I watch a YouTube videos which were awesome and put my locks in flawlessly. I followed everything. They said I even installed the Lock conversion relays because they recommended it. I also put a disconnect switch so that I can shut off my thunderbolts when I get my van serviced meaning that if you have a bulkhead with a door and a secure lock, you can go through that disconnect the thunderbolt, then go through the cargo door lock it and your contents are safe Overall, great experience from Thunderball company. They really take care of their customers.

Incredible product. I would highly recommend this Lock. customer service was top-notch. A1 service. Installation instructions are very good and detailed. I had some wiring questions. I called them on Saturday and they answered the phone. They went out of their way and did everything they could to help me get the locks up and running. They went above and beyond any service expectations I would expect from a company with sales and service. I tell everyone I know about them. I would definitely use them again.

Easy to install once I figured out the OEM lock wires I needed to connect to the thunderbolt locks. The Youtube videos were very helpful also.

Nice product, well thought out design. Install was straight forward. Biggest headache was figuring out the wire taps on the side door.
