Emergency in Montreal: Lost or Broken Car Key, What to Do?

Your heart stops for a moment: your car key is gone. Whether it fell out of your pocket during a walk on Mount Royal, broke off in the lock on a freezing morning in Laval, or is simply nowhere to be found, panic can quickly set in. Breathe. Fast and effective solutions exist.
Here are the steps to follow immediately when you face a car key emergency in the Montreal area.
1. Secure Your Vehicle
If you think your key has been stolen, the security of your car is the priority. If you are near your vehicle, make sure it is locked (if possible). If you are far away, avoid leaving valuables in plain sight.
2. Don’t Panic and Don’t Break Anything
Attempting to force the door or the ignition switch will only lead to much higher repair costs. Modern vehicles are equipped with complex security systems that make these attempts futile and damaging.
3. Call a Mobile Automotive Locksmith: The Fastest Solution
Instead of arranging a costly tow to a dealership and waiting several days, the most effective response is to contact a mobile locksmith service. This is the specialty of Maitre des Clés.
