Push Start Button Ignition Switch 2215450814 for Mercedes-Benz by AUTOMAJOR | Keyless engine start stop button. Fits C E S CL CLA CLS ML R GL GLA GLC G-Class. Replaces 2215450814

The AUTOMAJOR Push Start Button Ignition Switch is a direct OEM replacement designed for Mercedes-Benz vehicles equipped with keyless ignition systems. This switch replaces the worn or stuck factory push-to-start button on a wide range of Mercedes models from 1994 to 2024. This switch replaces Mercedes OEM A2215450814 (221-545-08-14), A2215450714 (221-545-07-14), A2215450514 (221-545-05-14), A2215459114 (221-545-91-14), and A221545071464 (221-545-07-14-64). Cross-references with aftermarket part numbers US1336 and SKUS1336. If your Mercedes-Benz uses any of these part numbers, this switch is the correct replacement. A failed push start button is one of the most frustrating Mercedes electrical issues. Common symptoms include: button feels stuck, sticky, or mushy when pressed, button presses but engine does not start, intermittent starting (works sometimes, not others), button rattles or makes noise when pressed, "Press Start" message appears but engine never cranks, button visibly worn or cracked from years of use, and complete failure to respond when pressed. These problems are caused by worn internal contacts and degraded button mechanism — replacing the button restores reliable, single-press starting. Replacing the push start button is a 15-30 minute DIY job with basic hand tools. Tools needed: trim removal tool or plastic pry bar, small flat screwdriver, and patience. Procedure: disconnect the negative battery terminal (recommended for safety), use the trim removal tool to carefully pry the dash trim panel containing the button (start at the corners and work around the perimeter), disconnect the electrical connector on the back of the old button assembly, transfer the button assembly to the new switch, reconnect the electrical connector, snap the trim panel back into the dash, reconnect the battery, and test operation. This switch fits Mercedes-Benz C-Class (C200, C220, C230, C240, C250, C280, C300, C320, C350, C400, C450, C43, C55, C63 AMG); E-Class (E200, E230, E240, E250, E280, E300, E320, E350, E400, E450, E500, E550, E63 AMG); S-Class (S400, S420, S430, S450, S500, S550, S560, S600, S63, S65 AMG); CL-Class (CL500, CL550, CL600, CL63, CL65 AMG); CLA-Class (CLA200, CLA250, CLA45 AMG); CLS-Class (CLS400, CLS500, CLS550, CLS63 AMG); ML-Class / GLE-Class (ML320, ML350, ML430, ML500, ML550, ML63, GLE350, GLE400, GLE450, GLE550, GLE63 AMG); R-Class (R320, R350, R500); GL-Class / GLS-Class (GL320, GL350, GL450, GL500, GL550, GL63, GLS450, GLS550, GLS580, GLS63); GLA-Class (GLA200, GLA250, GLA45); GLC-Class (GLC300, GLC350, GLC43, GLC63); GLK-Class (GLK250, GLK300, GLK350); SL-Class (SL400, SL450, SL500, SL550, SL600, SL63, SL65 AMG); SLK-Class / SLC-Class (SLK230, SLK280, SLK300, SLK320, SLK350, SLK55, SLC300, SLC43); and Sprinter and Metris vans.
