Electronic gate

Hi, Just moved about 6 weeks ago to a strata building that has a main electric security gate for the cars that needs a remote.     When I’m leaving and use the remote it opens quickly, but getting back in takes forever.  I’ve sat out there for 5 minutes clicking away until finally it works.  I’ve tried parking closer, further away and it doesn’t help.  What I’m wanting to know is as I probably need a new remote who  is responsible to pay for it,   the flat owner (me)  or the Strata corp?   Thanks.
