After experiencing problems with our Purple Line motormover I discovered that a new aerial mast has been installed next to the site where we store the van and that this is known to interfere with the frequency of the remote control causing the motormover not to function.
I have also been told that BT homehubs can also cause the same problem, which explains why it would not work when I parked overnight at on my nieces driveway.
As more sites are now providing Wi-fi then I suppose we can look forward to more problems.
It seems odd that a BT homehub should interfere, because that type of wireless device should be working in the 2.4GHz frequency bands, while the remote for your shifter should be (unless it's very old) using 433Mhz band - the two are miles apart.
Similarly, the aerial next to the site shouldn't interfere, as the 433Mhz band is reserved for low power devices, so any fixed, sizeable aerial should not be using it.
Assuming you've got fresh batteries in the remote, I'd suspect a fault in the antenna or transmitter/receiver in either the remote or the mover itself, such that pretty much any radio transmission nearby is swamping the signal.

The mechanic where we store our van said that this is a common problem with Purple Line motormover, don't know how old it is as it was on the van when we bought it last year, also the aerial mast near the site has only recently been fitted.
When we were there on Saturday he showed me how to reset the receiver which cleared the problem, I don't know the technicalities of it but that is what we were told.
If i have my remote control on my Enduro (which i fitted 6 years ago)switched on, i cannot lock or onlock my car with its remote.A similar thing happens when anyone rings my daughters door bell, the alarm on a car parked opposite goes off.So many things nowadays working on radio waves.
The BT Home Hub installations are notoriously "Dirty" and are known to cause interference to a variety of radio appliances by transmitting spurious emissions via harmonics right across the radio spectrum. There are currently a number of investigations by Offcom which are ongoing.
It has been mooted that BT are in direct contravention to the terms of the Wireless Telegraphy act but they have such a strong lobby that is difficult to bring them to task.
Not impossible though, anyone is at liberty to complain to Offcom and have their complaint investigated. If, however, the complaint is found to be unfounded then the complainant is liable to the Offcom costs, if upheld then no charge and the perpetrator will be dealt with.
I'm not too sure of where the 433mhz band is reserved for low power transmissions came from, My own licence allows me to use up to 400 watts on 433 mhz, not that I ever have, probably nearer 40 on the rare occasions I use the 70 cms band...........Mick
