Losing your car keys can happen to anyone — often at the most inconvenient time. Maybe you dropped them while rushing to work, left them in a shopping cart, or they simply disappeared somewhere at home. In a city like Montreal, where weather can be unpredictable and public transit isn’t always the easiest alternative, being stuck without your keys can be stressful.
The good news? You don’t need to tow your vehicle or wait days for a dealership. There are fast, on-site solutions available throughout Montreal — including same-day key cutting and programming right at your location.
Let’s walk through exactly what to do, step-by-step.
Step 1: Confirm the Keys Are Actually Lost
Before calling for replacement, it’s worth taking a moment to retrace your steps:
- Check bags, coat pockets, gym lockers, kitchen counters.
- Call your workplace, grocery store, or restaurant if you were recently there.
- For public places, Montreal’s Lost & Found services:
- STM (Metro / Bus): Check their lost items page.
- Shopping Malls (e.g., CF Carrefour Laval, Eaton Centre): Visit or call security desks.
- Parking Garages: Ask building security.
If you still cannot find your keys — it’s time to move to the next step.
DIY vs. Professional Car Key Replacement: Which Should You Choose?
Step 2: Identify Your Key Type
Not all car keys are the same, and the type affects price and replacement process. Here’s a quick reference:
| Key Type | Description | Cost Range (Approx.) |
| Traditional Key | Older models, no chip | $60 – $120 |
| Transponder Key | Contains chip for security | $120 – $200 |
| Remote Key + Blade | Unlock/lock + physical key | $150 – $280 |
| Smart Key / Push-to-Start Fob | No metal key, wireless | $250 – $450+ |
| Key Cards (e.g., Tesla) | Digital key access | Varies by model |
If you’re unsure which you have, don’t worry — most locksmiths can identify it using your car’s make, model, and year.
Step 3: Should You Call a Dealership or a Locksmith?
Dealership
- Pros: Original manufacturer parts.
- Cons: Requires towing, higher cost, longer wait time (often 1–3 days).
Local Automotive Locksmith (Recommended)
- Pros: Comes to your location anywhere in Montreal, cuts & programs on-site, usually cheaper than dealership.
- Cons: Must choose a trained locksmith with proper programming tools.
In most cases, a certified mobile locksmith in Montreal is the fastest and most cost-effective solution.
Step 4: Get These Details Ready
Before calling:
- Car make, model, and year
- Your location in Montreal
- VIN number (found on driver’s side door frame or dashboard)
- Proof of vehicle ownership (for security and authorization)
Providing this info helps the locksmith determine:
- Replacement key type
- Programming requirements
- Accurate cost and time estimate
Step 5: Call a 24/7 Car Key Replacement Service in Montreal
Most mobile locksmiths can:
- Create new keys without the original
- Cut the key on-site
- Program transponder / smart key chips
- Replace broken, snapped, or damaged keys
- Unlock your vehicle if you’re locked out
Average time to complete service:
20 to 45 minutes, depending on key type.
Step 6: If Your Key Was Stolen
If you believe someone may have your key, don’t just replace it — deactivate the old one.
A locksmith can:
- Reprogram your car so stolen keys no longer work.
- Update your security codes.
- Provide a new working key.
This protects your vehicle from theft.
