Losing your car key can quickly turn a regular day into a frustrating one—especially in a busy city like Montreal. Whether you’re stuck outside your vehicle in the middle of winter or can’t find your key right before heading to work, the inconvenience is real. One of the first questions people ask in this situation is, “How much will it cost me to replace this key?”
In this guide, we’ll break down the different types of car keys, the factors that affect pricing, and how to find the most cost-effective solution in Montreal.
Understanding the Types of Car Keys
The type of key you have plays a major role in how much you’ll pay for a replacement. Here’s a breakdown of the most common types:
Traditional Metal Keys
These are basic mechanical keys with no electronic components. They’re typically found in older cars and are the least expensive to replace.
Transponder Keys
These keys contain a small chip that communicates with the car’s immobilizer system. They require both cutting and programming.
Remote Key Fobs
Remote keys allow you to lock and unlock your car from a distance. Some also contain the ignition key, while others are separate. Replacing these requires syncing with your vehicle’s onboard computer.
Smart Keys and Push-to-Start Systems
Smart keys operate wirelessly and allow for keyless entry and ignition. They’re the most technologically advanced—and usually the most expensive to replace.
Laser-Cut Keys
These keys have a more complex cut than traditional ones and often require specialized equipment for duplication. They are typically more secure but come with a higher replacement cost.
