What is the reason why the Renault Koleos keyless entry can lock but cannot unlock?
2 Answers
Renault Koleos keyless entry can lock but cannot unlock for the following reasons: 1. Signal interference: When the car detects the key, the signal is interfered by mobile phones, access cards, dash cams, or parking location, preventing the vehicle from sensing the car key. 2. Low battery: This situation can also cause the car to fail to detect the key. The car key battery needs to be replaced to resume normal operation of the smart keyless entry system. 3. Faulty sensing chip: This requires professional inspection at a 4S shop for accurate diagnosis. 4. Pressing the door sensor area: In this case, when opening the door, the car has already detected the smart key and automatically unlocked the door. However, the owner or driver accidentally pressed the door sensor area first while opening the door, causing the car door to lock.
I've spent several years at the auto repair shop and encountered many Renault Koleos owners complaining about the keyless entry system only locking but not unlocking. The most common cause is a dead remote key fob battery, especially the CR2032 coin cell type. When it's low on power after prolonged use, it can't send the unlock signal but still responds to the lock command. Don't underestimate this issue - it's frustrating when your car won't open outside. I once helped a neighbor fix this by simply replacing the drained battery. If a new battery doesn't solve it, the problem might be a faulty sensor inside the door handle (not triggering when touched) or a malfunctioning signal receiver module. My advice: first try checking/replacing the key battery yourself (just costs a few bucks). If that doesn't work, visit the dealership for computer diagnostics to prevent damaging more components. The Koleos system is quite sensitive, so keep your key dry and protected from impacts to extend its lifespan.
