  • Does what it's supposed to, just wish more work time
This unit I bought as I deal with a lit of suspect key fobs, and this was a very cheap way to tell you. Wish it had a signal meter, but then $39, vs a $700 tPMS tool I was using, I definitely can't complain. Picked up the fobs at 900,434, and 315 with no issues. The fob has to be roughly a foot away however at max, anymore and won't pick it up. Picked up a friend's ham radio also lol (asked him to see if it would and he transmitted a few feet away) One surprise was IR for tv remotes and it will also pickup the pulse ring for anti- theft keys (on keyed vehicles, there is a ring that sends out a charge to "ping" the key and many times I've had to guess if it was bad, but tried on a Ford and picked up the loop ! Only real con I have is on time. Most test tools stay on 5 minutes before timing out, this one shuts down after about 2 even if you are using it. Flipping it back on, it works, but I rather a longer use time. So if you work or around vehicle or home key fob systems, very cheap price for a good tool. ... show more

  • If you know you know
I purchased the LAUNCH Remote Key Frequency Tester for use in a professional automotive environment, and it has quickly become a standard tool on my diagnostic bench. This tester does exactly what it claims, it provides fast, accurate RF signal verification for key fobs, remotes, and smart keys across all MHz ranges. From a technician perspective, this eliminates a lot of guesswork during immobilizer and remote programming jobs. Instead of assuming a key battery or remote is bad, I can instantly confirm whether the fob is actually transmitting and at what frequency. The response time is immediate when a button is pressed, and the signal feedback has been consistent across OEM and aftermarket keys. This tool has already proven valuable in several situations verifying weak transmitters, confirming customer-supplied aftermarket remotes that were out of spec, and ruling out vehicle-side receiver issues during diagnostics. It’s especially useful when customers come in claiming “the key stopped working,” because we can test and document results on the spot. Build quality is solid, the display is clear, and the unit is compact enough to keep at the service counter or work bay. No setup, no software, and no learning curve just power it on and test. For any shop that programs keys, services immobilizer systems, or handles remote start troubleshooting, this is a practical and cost effective tool that adds credibility to diagnostics and saves time on every job. Highly recommended for professional and personal use. ... show more

  • Well made, quick easy use, great size
Works well, great for quick diagnostics of start system in vehicles. Helps with making sure key is sending signals and if vehicle is looking for signals.

  • Good Functionality
Costs more than some but only requires proximity to the transmitter-- it does not have to be in full contact with the tester, which appears to be a requirement with the lowest-cost testers. Mine works great and I'm glad I finally got one. Key tags that I was about to toss apparently just need to be reprogrammed, great to know since mine are discontinued items that are hard to source. Worth noting that the webpage has a seller warning, but my shipping was fast and on target, and the item appears to be of good enough quality to last and was well-packed. ... show more

  • Very Useful
This device was useful in determining which old fobs were not working before I tried programming them...Like this a lot.

  • Good quality
The indicator lights are a bit pale for old eyes in a lighted environment. The 30 second timeout is really short. Works,
