The homeowner stepped closer.
"Why?"
The technician pointed toward the lock assembly.
"That's not quite how I remember it."
The engineer studied the metal.
The finish looked newer.
One protective screw had been replaced with a slightly different head.
The lock still functioned.
But the technician's observation troubled him.
He photographed the assembly.
Then arranged for the security contractor to inspect it.
The contractor later found that the gate's cylinder had been replaced with a compatible unit.
The replacement did not prove who installed it.
But it explained why a different key might operate the gate.
The homeowner felt furious.
His private security hardware had apparently been changed without his permission.
And he had no idea when.
He searched his maintenance records.
No approved gate replacement.
No invoice.
No contractor appointment.
Nothing.
Then he remembered the HOA notice.
Community safety access requirements.
The president had demanded credentials.
When he refused, someone apparently found another way to obtain access.
He contacted his attorney again.
The attorney advised him to preserve the old hardware, maintain the camera records, and file an appropriate report if he had evidence of unlawful entry or damage.
The engineer followed that advice.
He had the compromised lock replaced by a qualified professional with a properly controlled key system.
For several days afterward, the signs of intrusion stopped.
Then the HOA president sent another notice.
This time, the subject read:
EMERGENCY ACCESS OBSTRUCTION.
The homeowner stared.
The letter claimed he had interfered with community safety by changing the pool-gate lock without HOA approval.
It demanded that he provide new access.
He almost laughed.
Instead, he forwarded it to his attorney.
Then added the notice to his growing evidence file.
The pattern was no longer subtle.
Someone inside the HOA wanted a working key to his pool.
And the president was willing to invent administrative problems to get one.
