Case study

EOL test for car key

Keyless Go is a common feature in modern cars. To trust this feature, the function and security of the car key must of course be ensured. One of our customers required a fully automatic test system to fulfill this purpose. This system was to test both the integrated PCB (front end) and the fully assembled key (back end).

Testing in a
shielded environment

Vollautomatische Montageanlage für einen KFZ-Funkschlüssel mit den End-of-Line-Test in einer abgeschirmten Testumgebung
Eine Rundtaktanlage, bei der die Haptik der Tasten von Fahrzeugschlüsseln geprüft werden. Dadurch ist der Endkunde sicher, dass sein Schlüssel korrekt funktioniert.


ENGMATEC developed an efficient EOL solution that verifies the functions of the keyless entry system in a shielded and reproducible test environment. To verify the assembly and ensure handling comfort, a precise haptic test is performed for each individual key. This test is conducted in a particularly space-saving way in the rotary indexing table. A visual inspection verifies the quality of the keys.

The products are also tested in certified interference-free test chambers to ensure high-frequency and ultra-wideband functionality – on two tracks for a short cycle time. This ensures both communication functions and theft protection.
