Wireless door lock can only lock

I added a 10µF ceramic capacitor to the existing (small) ones.
This considerably increased the fob's range (before 3m, afterwards 10m).
I measured the battery's ESR which was about 17 ohms, which might be a reason for the low range before.
No, I don't want to buy a new battery yet ;)

great, but that can be a catch 22. a farther range could mean a farther possibility of accidentally pressing the unlock button. our cars re-arm only after 30sec.
