Remote Control Opens But Doesn't Lock Car – Solution with a Certified Locksmith in Puerto Rico
Why does the remote unlock but not lock the vehicle?
When the remote key fob unlocks the doors but doesn't lock them, the problem isn't always the battery. As a Certified Locksmith in Puerto Rico , I can say that this issue is usually related to the button, the signal, or the vehicle's system.

Damaged or worn-out closure button
The button may be internally broken or worn out, so it doesn't send a signal even though the open button works.
Partial failure in the control circuit
The key fob may have internal damage that affects only a specific function.
Other common causes of the problem
Partial reprogramming of the remote control
The control may lose synchronization in certain functions, affecting only the closing.
Problems with the vehicle's locking actuator or system
The car may receive the signal, but fail to lock due to faults in doors or modules.
What can you try before calling?
Press the button more firmly
If the button is worn, it may require more pressure to make contact.
Try another controller if you have one available.
This helps determine if the problem is with the control unit or the vehicle.
