Mercedes Sprinter Key Problems: First Warning Signs

Knowing if your Mercedes Sprinter key is going to fail is invaluable to avoid a vehicular headache, and there are a few telltale signs to look out for to spot incoming problems and know whether you need to fix your Sprinter key.

Firstly, trouble turning the key in the ignition, dashboard warning lights, or the key not turning at all are some of the most common issues; along with the doors not locking or unlocking, problems arming the alarm, and the electronic steering lock failing to disengage.

Here’s what to look out for:

Key unable to turn: The most common issue is that the key is unable to physically turn in the ignition. This is often due to damage or wear to the key itself.

Rough ignition process: The vehicle may start, but if the turning process and putting in and extraction of the key feel difficult, the key may have some physical damage.

ESL issue: If the key doesn’t turn correctly in the ignition, this can prevent the ESL (Electronic Steering Lock) from disengaging, which has been found to be a common issue in Sprinters.

Warning lights: If warning lights illuminate on your dashboard or electronic system, it can signify key-related issues, along with other electronic problems such as the vehicle battery.

Why could this be happening?

• Battery needs changing: The battery in the fob could be weak or dead, causing functionality issues.

• Wear on the ignition switch: The switch in the ignition itself could be damaged, forcing the key to not work correctly.

• Strong radio signals: Uncommon, but very strong radio signals in the area could mask your remote’s signal.

• Electronic Issues: A problem with the vehicle's communication module or fuses can also prevent the vehicle from starting. 

What to Do

Swapping the battery in your key fob would be the first process of elimination to find the fault; otherwise, consult with Spinter key replacement and repair specialists if the problem persists.
