Why are my Kia Stonics power door locks not responding to the remote in hot weather?

I’ve noticed that during hot afternoons in Karachi, my Kia Stonic’s power door locks often stop responding to the remote key. Sometimes I have to press the unlock button multiple times, o r manually unlock the driver-side door. Has anyone else experienced this issue in Pakistan’s summer heat? Could it be related to the actuator, the remote battery, o r a wiring issue? Looking for advice o r similar experiences.

Yes, this is a relatively common issue in regions like Karachi, Multan, and other hot cities of Pakistan, especially during summer when temperatures rise above 40°C.

The problem could be due to:

Overheating of door lock actuators: High temperatures can cause the actuators to temporarily malfunction o r slow down.

Weak remote battery: Heat may reduce the efficiency of the battery inside your key fob.

Sun damage o r heat stress on internal wiring in the doors, which can affect the central locking system.

Recommended steps:

Replace the remote battery first—it’s a cheap and quick fix.

If the issue persists, get the door lock actuators checked. Sometimes lubricating o r replacing them resolves the issue.

Park in shaded areas whenever possible to avoid direct heat buildup inside the vehicle.

A dealer-level diagnostic scan may also reveal if theres a deeper electrical fault.

This issue usually worsens with time if ignored, so its worth getting it checked early.
