Mercedes remote key button — restore instant unlocking
A Mercedes remote key button that only responds after three presses is one of the most frustrating everyday faults. This 6-pin SMD microswitch restores your key to its day-one precision, without replacing the shell, buying a whole new housing, or reprogramming. An affordable, long-lasting repair that is highly recommended by GLK and GLA owners.
A component designed for your Mercedes GLK and GLA
This key control button exactly matches the original format of the switch found on Mercedes "arrowhead" style remotes and three-button keys. Its six pins fit the same pads as the original part, ensuring perfect alignment of the lock, unlock, and trunk release buttons. No play, no misalignment: the click becomes crisp again and the button press feels firm.
Technology, quality & finish
The switch is a metal dome SMD tactile switch designed to withstand tens of thousands of presses. The contacts are treated to resist oxidation, the main cause of the original failure: corrosion of the dome eventually prevents current from flowing, making the remote temperamental. The plastic housing withstands the heat of the soldering iron and supports the temperatures found in a pocket or car interior in midsummer without deforming.
Installation, compatibility & durability
Replacement is done with a fine-tip soldering iron after opening the key shell and desoldering the old microswitch. Allow about fifteen minutes for a careful DIYer. No reprogramming is necessary, as the original chip and circuit remain in place. Compatible with many Mercedes remotes, including GLK and GLA; always compare the pin layout and dimensions with your original switch before ordering, as formats vary depending on the year and key version.
