User Reviews

ShiftLock is a specialized tool for tow and repossession professionals that many users find valuable for quickly locating shift-release information. Reviewers praise its usefulness, long-standing reliability, and a growing catalog of models through regular updates, with several noting it has paid for itself. However, multiple reviews point to limited content—too few models and years—poor or unclear photos, and outdated data due to infrequent updates. Some users also question the value given the price. Overall, it’s helpful but could become essential with broader coverage, better visuals, and more timely updates.
Pros
  • Very useful tool for towing and repossession work; provides wealth of information at your fingertips.
  • Easy to find information and keep things organized.
  • Content updates over time with new car models and additions; app continues to grow.
  • Valuable resource that has saved users time and money, with several noting it pays for itself.
Cons
  • Limited model and year coverage; many makes/models are missing or not listed.
  • Photos are frequently poor, unclear, or not representative of the model.
  • Data feels outdated or not updated frequently enough to reflect new releases.
  • Value for money concerns; as a paid app, many users want more content or lower price.

The pictures are horrible and it has no newer models

It is a great app. It has helped me numerous times, but it needs to be updated more often. I kinda wish there was another app like it, as a back up

Not much content. You can’t select Models or go by Years and a lot of the pictures are next to useless. In the time it takes to use this app, you can go online and find a Free video… or just drag it out and tow it from the drive wheels. Realize a lot of newer vehicles don’t have a Manual Neutral Release anyway.
