Interesting. I'm stunned at how far away my remote works, I can stand on the opposite long end of a footy field and a bit further back and it still works.

I'm not sure if the frequency has anything to do with range or interference, but my key fob remote is 27mHz.
I went to get a second remote from a locksmith that does car keys and fobs and apparently 27mHz is too low for their machine to read and therefore can't code a second fob from my factory one.
Thanks everyone....i may have old timers.... tried the spare key and it worked fine...so i thought i'd check the battery in the key FOB i use, after opening up the FOB i could see that in fact I had not replaced the battery :oops: IDIOTO... quick trip to the supermarket got a new battery and replaced it..alla kazam great success, it worked.
thanks again for your help in my non issue
Cheers

27mhz is really low for this kind of thing - usaully 315hz or 433mhz. A lower number in mhz means longer wavelengths, therefore better penetration and range. The surrounding environment can do weird things with reflections and interference - check this story out https://www.rtl-sdr.com/solving-the-...uncube-dongle/
My remote is half buggered, too many button presses in nearly 200,000.
I lock & unlock with the key.
The plus side is I'm not transmitting my lock/unlock signal to anyone dodgy who might be hanging around with a tool to read/replicate such signals to rob me of my vehicular contents. Call me mr paranoid, country dude who moved to the city and doesn't trust anyone.
