When You Need Help With Lost Or Stolen Car Keys

Losing your only car key or having it stolen can feel stressful, but you’ve got practical options. Common situations we handle every day include:

• Lost car keys at home, work, the gym, or while shopping
• Stolen car keys taken with a bag, jacket, or from the post
• Locked out of your car with no spare to hand
• Moving house or changing tenants and needing old keys rendered unusable
• Concern your vehicle could be at risk if someone finds or has your keys

Typical symptoms and scenarios:

• Car won’t unlock or start because you have no working key/fob
• Central locking working, but you don’t have a programmed key to start the engine
• Immobiliser light or key symbol on the dash when attempting to start
• Worry about vehicle theft after a set of keys goes missing

If any of the above applies, we can help with urgent vehicle entry, immobiliser reprogramming, and new keys cut and coded right where you are.

What To Do Immediately If Your Keys Are Lost Or Stolen

• Stay calm and note your exact location and vehicle details (make, model, year, registration).
• If you believe the keys were stolen, report it to the police and obtain a crime reference number.
• If there’s a risk of the vehicle being taken, consider moving it to a secure spot or using a steering lock until we arrive.
• Contact your insurer to check key cover; we can provide an invoice for any claim.
• Call our Bromley team for fast assistance and clear next steps.

How We Solve Lost Or Stolen Car Key Problems

We follow a proven process designed for speed, security, and non-destructive methods wherever possible. Our mobile vans are fully equipped with dealer-level diagnostics, key cutting machines, and programming tools to handle modern immobiliser and smart key systems.

• Secure, Non-Destructive Vehicle Entry

  • We unlock your car using specialist tools and techniques designed to protect your locks and paintwork wherever possible. In the rare event that destructive entry is the only safe option (e.g., severe lock damage), we’ll explain the reasons and get your approval first.

• Immobiliser & Key Data Management

  • For lost or stolen keys, we can erase missing keys from your vehicle’s memory and add new ones so the old keys will no longer start the engine. We use OBD2 diagnostics for most vehicles and EEPROM/ECU programming for models that require advanced procedures.

• On-the-Spot Car Key Replacement & Programming

  • We cut and code new keys on site. That includes:
    • Transponder key programming (chip keys that talk to your immobiliser)
    • Smart key programming for proximity and push-to-start systems
    • Remote key programming and key fob replacement
    • Key blade cutting, including laser cut/high-security vehicle keys

• Optional Lock Changes or Ignition Work

  • If you want complete peace of mind after a theft, we can replace door locks, boot locks, and ignition barrels, and then program new keys. We also repair worn or damaged locks when needed.

• Final Testing & Handover

  • We test lock/unlock, remote functions, and starting to ensure everything works smoothly, then provide a warranty on workmanship and keys.

3. Secure Entry And Assessment

• We unlock the vehicle non-destructively wherever possible, verify ownership, and confirm the best approach.

Security And Peace Of Mind After Key Loss Or Theft

We understand the anxiety that follows lost or stolen car keys. In many cases, immobiliser programming alone is enough to protect you—once we erase the lost/stolen key from your vehicle’s memory, it won’t start your car. For additional reassurance, particularly after confirmed theft, we can:

• Replace locks and ignition barrels
• Recode door locks to new key profiles
• Provide spare keys and advice on key security, tagging, and storage
• Assess your vehicle security and recommend upgrades

Costs And Quotes

Every job is unique. The price depends on:

• Your vehicle’s make, model, and year
• The type of key (basic transponder, remote fob, smart/proximity)
• Whether programming is via OBD2 or requires EEPROM/ECU work
• Whether lock changes are requested in addition to key replacement
• Timing (standard hours or emergency call-out)

FAQs: Lost Or Stolen Car Keys

Can a locksmith make a car key without the original?

Yes. We can create and program a new key without the original by accessing your vehicle’s immobiliser data. We typically use OBD2 diagnostics, and for some models we may perform EEPROM/ECU programming. This allows us to cut and code a new key that starts your car safely.

What should I do if my car keys are stolen in the UK?

Report the theft to the police and obtain a crime reference number, inform your insurer, and call a trusted local auto locksmith. We can erase the stolen keys from your vehicle’s memory and supply/programme new keys so the thieves can’t start your car.

Can you stop my lost or stolen key from working?

Yes. We can remove lost or stolen keys from the car’s immobiliser so they won’t start the vehicle. If you’d like maximum security, we can also replace locks and ignition barrels.

How long does it take to get a new car key?

Most vehicles can be completed in a single visit. The time depends on your make/model and whether advanced programming is required. We’ll give you a realistic timeframe when you call.

Do you cover smart keys and push-to-start systems?

Absolutely. We handle smart key programming, proximity keys, and push-to-start systems for a wide range of brands, using dealer-level equipment.

Will you damage my car when unlocking it?

We use non-destructive entry techniques wherever possible. In rare cases where a lock is already damaged or a particular model requires a different approach, we’ll explain the options and seek approval before proceeding.

Is a dealer my only option?

No. A local mobile auto locksmith can often help faster and more conveniently than a dealer, especially when you have no key at all. We come to you, unlock the vehicle, and programme new keys on site.
