Testing remote fobs

[omglol]

How do you guys test if remote fobs are transmitting OK? I have simple Sealey tool (Sealey VS921 IR & RF Key Fob Tester | eBay (http://www.ebay.co.uk/itm/Sealey-VS921-IR-RF-Key-Fob-Tester-/251457308694)), but this one can only tell if the fob is transmitting "something" or "nothing at all".

Is there a more sophisticated key fob tester, that actually displays data sent by the remote or something ... or some other tool for this job, so you can be 100% sure the fob is working properly? Thanks!

Well, this two ones are basically the same as mine. Especially the first one. They just tell you if the fob is transmitting something or not, but they show nothing about the data transmitted.

A wide-band receiver works very well.

Yaesu made one in the past but I think they are out of business now. If you can find one. Works very well. Tells you frequency and everything.
