Blimey what a difference it makes, just putting the alarm on and off, before sometimes when it was bad the "reach" of the alarm was terrible, i was having to put the key fob up against the window sometimes to unlock it, locking the door that was already locked to unlock it!!! the best i ever hope to get was 2m away (if i was lucky), now that i have changed it to the new one i went across the road 10m away and it locked it, i don't know what my maximum distance is yet, for the "reach" of it, but i’m well happy, it took literarily 5 mins to do, take the parcel shelf out fold up the back seat on the drivers side, pop out 5 press studs, and unhook the 3 latches against the window, (or just 1 or 2 and use a stubby Phillips screwdriver) unscrew the 1 screw holing the part down, pull it up at and angle and take out the 2 connectors, put them in the new part, angle the part so the lug goes back in screw it down again, and push the parcel shelf home, 5 push studs back in, parcel shelf back on and the jobs a good’un it took me just 5 mins to do, (I timed it)
Hopefully the reason I changed it has also been sorted out, BMC staying alive most of the night (and day) draining my battery 24/7 and also the lock out when I go to built up arias with people using gadgets with 433 Mhz the old part had a lot wider bandwidth so it would pick up over and under that bandwidth, it now ONLY picks up 433 Mhz
