Créer un assistant vocal IA pour serrurier (24/24) en quelques minutes : Ne laissez plus le répondeur vous faire perdre des clients

In the locksmith profession, every call counts. An emergency, a slammed door, a broken key… and a customer expects an immediate response. The problem is that you cannot be available permanently, nor answer multiple calls at the same time.

Result: missed calls, lost opportunities, frustrated customers.

In this tutorial, you will see how to create in a few minutes an AI voice assistant capable of answering the phone 24/7, qualifying requests, reassuring customers, and forwarding only relevant interventions to you.

Why an AI voice assistant is strategic for a locksmith

A locksmith does not only sell a service. He sells the ability to intervene quickly in a stressful situation.

When a customer calls:

  • they are often locked out
  • they are in a hurry
  • they are worried about the price
  • they want an immediate answer

A well-configured AI voice assistant allows you to:

  • answer each call instantly
  • reassure with a professional and human tone
  • collect all useful information (address, urgency, type of problem)
  • filter out non-relevant requests
  • save you considerable time

And above all: never a busy line again.

Tutorial objective

Create a voice assistant for a locksmith capable of:

  • automatically answering incoming calls
  • qualifying emergencies (broken key, blocked door, etc.)
  • collecting customer information
  • announcing a price range
  • offering a rapid intervention
  • sending a summary by email
  • handling multiple calls simultaneously

Step 1: Obtain a phone number

First step: have a number linked to your assistant.

In the ALLO application:

  • check the available numbers on your account
  • if no number is available, purchase one directly
  • select a number in France
  • choose from the suggested options

This number becomes your entry point.

Field tip: use a dedicated number for support or emergencies. This allows you to accurately measure your incoming call volume.

Step 2: Create a specialized locksmith voice agent

In the left-hand menu:

  • click on “Agent”
  • create a new agent

To move quickly, use an existing template:

  • select “use a template”
  • search for “locksmith”
  • choose the template dedicated to locksmith appointment booking

This template already contains an optimized structure:

  • greeting
  • qualification
  • information collection
  • conclusion

Step 3: Enter your company information

This is where you transform a generic agent into a business assistant.

Concrete example:

  • Name: Express Métal
  • Intervention time: 1 hour
  • Rates: between €150 and €280
  • Payment methods: card and cash
  • Intervention area: Orléans
  • Availability: 24/7

This information is essential. It allows the agent to:

  • respond accurately
  • reassure regarding deadlines
  • set expectations on price
  • Avoid misunderstandings

Step 4: Customize the voice and behavior

Give your assistant an identity:

  • Name: for example “Samantha”
  • Voice: Marine (recommended for a natural output)
  • Language: French
  • Automatic language detection enabled

Key advantage: if a customer calls in another language, the agent adapts automatically.

Recommended settings:

  • Speed: 1.5 for a smooth conversation
  • Tone: friendly and helpful
  • Temperature (creativity): 0.8 for more naturalness

Objective: a reassuring, professional voice, never aggressive.

Step 5: Configure conversational behavior

Two modes exist:

  • Workflow mode (scripted)
  • Free mode (natural conversation)

For a locksmith, prioritize free mode.

Why?
Because every situation is different. A stressed customer does not follow a script.

The model already includes:

  • a greeting message
  • qualification instructions
  • information to retrieve

You can customize everything:

  • modify the script
  • add rules
  • define limits

Example of expected behavior:

  • rephrase the problem
  • ask precise questions
  • reassure
  • propose a quick solution

Step 6: Activate key features

For a locksmith use case, here are the essential settings:

Language detection
Essential if you operate in tourist or urban areas.

Appointment Scheduling
By connecting your calendar, the agent can:

  • propose a time slot
  • schedule an intervention
  • automatically fill your schedule

Summary email
After each call, you receive:

  • the customer’s contact details
  • the problem
  • the address
  • useful details

This is a huge time saver.

Incoming calls only
Disable outbound campaigns if you only handle incoming calls.

Step 7: Connect the number to the agent

Once the agent is created:

  • go to “incoming connection”
  • create a new connection
  • associate:
    • your agent
    • your phone number

From that point, your assistant is operational.

Step 8: Real test (simulation)

Example call:

A customer calls, locked out with a broken key.

The agent will:

  • greet with a professional tone
  • rephrase the problem
  • ask questions (door closed? location?)
  • collect:
    • name
    • number
    • address
    • entry code
  • provide a price estimate
  • specify payment methods
  • reassure about response speed
  • confirm the information
  • announce a quick callback

What is key here:

  • empathy (“I understand this is stressful”)
  • structure (questions → info → solution)
  • clarity (no unnecessary jargon)

Concrete result for a locksmith

Once in place, your assistant enables you to:

  • never miss a call again
  • handle multiple calls simultaneously
  • filter requests
  • receive complete client sheets
  • intervene only where it is profitable

And above all:
you regain control of your time.

What makes the difference (and few do it)

  1. Rephrasing
    The agent repeats the information to avoid any errors.
  2. Price transparency
    A range is provided, with no surprises.
  3. Structured collection
    Name, address, code, phone → everything is ready before intervention.
  4. Customer stress management
    An upset customer is calmed, without friction.
  5. Total availability
    Even at 3 a.m., someone answers.

Conclusion

In a profession like locksmithing, response speed makes the difference between winning a client… and losing one.

  • better qualification
  • less stress
  • more profitability

You keep control. The AI handles the rest.
