🔑 First — Don’t Panic, Do This

Before assuming your keys are gone for good:

✅ 1. Retrace Your Steps

Check pockets, bags, and recent locations
Think: last place you used your keys

✅ 2. Check Inside the Car

On seats
Under seats
In the boot

👉 It happens more often than you think.

✅ 3. Ask Around

Friends, family, work reception
Shops or venues you visited

🚨 If Your Keys Are Truly Lost

Once you’re sure they’re gone, you have 2 main options:

🔧 Option 1: Call a Mobile Car Locksmith (Fastest Option)

This is usually the quickest and most cost-effective solution.

A mobile locksmith can:

Come to your location
Cut a new key on-site
Program the key to your car
Get you driving again fast

🏢 Option 2: Go Through the Dealership

Dealerships can replace keys, but:

Slower (often days)
More expensive

👉 Best for rare or highly specialised keys only.

🔹 Standard Metal Key

No programming required

🔹 Transponder Key

Needs programming to start the car

🔹 Remote / Key Fob
