Well I did install the one with the last four digits of 5326. It is on the list in the XF documents page that has the lock/unlock beep. It only beeps though when unlocking and not when locking. So I’m not sure if I did something when installing it that disabled the unlock beeping feature. I have to get under the cowl again anyways so I’ll see if I can’t get it to work properly. The main reason I bought it is for the locking 3 chirp feature. So I’ll see soon enough if it’s something simple I might’ve missed, or if I didn’t properly disengage the old one and that had something to do with it. 🤷🏼‍♂️
