A landlord is required to provide reasonable accommodation to tenants with disabilities that meet the definition of "disability" under the California Fair Employment and Housing Act, unless providing the reasonable accommodation would be an undue hardship on the property owner. If you required the additional gate opener because of a disability, the landlord is required to interact with you in a timely manner regarding your need.
You may want to send a certified letter (keeping a copy for yourself) with reference to the Fair Employment and Housing Act and see if that gets you any result.
