The follow-up message is the cheapest marketing a locksmith can do

17 August 2026 · 4 min read

Ask a locksmith where new customers come from and you will hear "Google" and "word of mouth". Both are true, and both are downstream of the same thing: what a customer remembers and says about you after the job.

Here is the uncomfortable part. The customer's memory of you is formed in the day or two after you drive away, and most locksmiths are completely silent during that window. The follow-up message exists to own it.

Why the follow-up works so well in this trade

Locksmith work has an unusual shape compared to most services:

• It is an emergency purchase. The customer did not compare five providers. They took whoever answered and arrived. Loyalty at this point is zero; you were a phone number.
• It is infrequent. A typical customer needs you every couple of years. If they have to search again next time, you are back in the Google lottery against every competitor and every fake listing.
• Trust is the whole product. You handled their car's keys. A locksmith who checks in afterwards reads as a professional running a real business, which is exactly the impression that gets you recommended to a brother-in-law.

One short message converts "a phone number that showed up" into "my locksmith". That phrase, said to a friend, is worth more than any ad you can buy.

What to send, and when

You do not need a marketing department. You need one honest message, well timed.

Timing. The day after the job is the sweet spot. Same-day can feel like part of the transaction. A week later, the moment has cooled. Next-day says: the job is done, and I still care that it went well.

The message. Short, personal, specific to the job:

Hi Andrei, this is Alex from the locksmith service. Just checking the new key for your Golf is working fine. Anything off, write me here.

That is the whole trick. It names the person, the job and the car, and it opens a channel.

Then branch on the reply:

• Happy customer. Thank them, and only now ask for the Google review, with a direct link. A review request lands best in the warm moment right after someone told you everything works. Ask once; if they reviewed you recently or do not respond, let it rest.
• Unhappy customer. This is the message earning its keep. A key that sticks or a remote that drops pairing becomes a warranty visit and a saved reputation, instead of a one-star review you discover a month later.

Why WhatsApp. In most of Europe it is where customers actually reply. A missed call from an unknown number gets ignored; a WhatsApp message from the person who made their key yesterday gets answered.

The rules: consent is not optional

A follow-up program that annoys people is worse than none, and in the EU the rules have teeth (GDPR, plus national rules on electronic communication):

• Ask at the job. "I will message you tomorrow to check everything works, OK?" Almost everyone says yes, and now the message is expected, not cold.
• Stop means stop. If someone replies "stop" or asks you not to write again, that contact is closed permanently. No exceptions, no "one last message".
• Service first, sales never. A check-in about the work you did is a service message. A promotion blast to your whole contact list is spam, legally and socially.
• Do not over-ask for reviews. One request per happy job at most, and if the same customer returns within a few months, skip the ask entirely.

Doing it manually vs. automatically

Nothing above requires software. A disciplined locksmith with a notebook can do all of it. The catch is the word disciplined: the follow-up is due at exactly the moment you are elbow-deep in the next job, and after a twelve-hour day, "I will send them tomorrow" becomes never. Manual follow-up programs do not fail from bad intentions; they fail from busy Tuesdays.

This is why we made follow-ups a core module of Nyrano rather than an add-on. When a job is marked paid, the check-in goes out on WhatsApp on its own, replies land back where you can see them, happy customers get the review link, unhappy ones get flagged to you immediately, and stop requests are honored automatically. The judgment stays yours; the remembering is the machine's.

However you run it, with our tool or a notebook, start this week: message yesterday's customer and ask if the key works. It is ten seconds of typing, and it is the highest-return marketing in this trade. If you would rather never have to remember it, book a live demo and see the automated version.
