Sorry, there was a problem. Please try again later.We could not find specific information about replacing the Eufy S231 with a new model, such as the FamiLock S3 Max, including whether a locksmith will be required. However, if your current installation required precise alignment and detailed work by a locksmith, it is possible that similar attention to alignment may be necessary for the new model. For precise compatibility and installation details, it's advised to confirm that the fitting dimensions of the replacement model match the existing setup. Also, instructions provided with the FamiLock S3 Max may clarify whether any special tools or professional help are needed, making the process smoother.
