Your door reader operates at 125kHz but the pet chip may be a 132.5kHz device
according to:-
"Europe uses International Standards Organisation (ISO) regulation chips, which
operate at a frequency of 132.5 kHz (also known as FDX-B chips), while the US
uses an older style, 125 kHz chip (known as FDX-A). "
