Experiencing issues with your 2015 BMW key fob, specifically with the comfort access feature? You’re not alone. Many BMW owners encounter frustrating situations where their key fob becomes unresponsive, leaving them locked out or struggling to access their vehicle. This article explores a common problem reported by a 2015 BMW owner and offers insights into potential causes and solutions.
The owner described an intermittent issue where the comfort access system, which usually allows unlocking the car by simply grabbing the driver’s door handle, failed to function. Typically, locking the car was done via the rear door touchpad, and unlocking was seamless with the driver’s door handle. However, the problem arose when unlocking became unreliable, forcing reliance on the physical button on the key fob itself. Interestingly, this issue seemed to coincide with warmer weather, suggesting a possible temperature-related component malfunction. Once unlocked with the fob button, the touchpads would regain functionality, only to become unresponsive again after a period.
Adding to the mystery, a separate incident highlighted a potential safety “feature” or related issue. When the key fob was accidentally locked inside the car (through an open window), neither the door touchpad nor the interior lock/unlock button would operate. The owner speculated that the car might have detected the fob inside and disabled these functions, possibly as a safety measure. This incident raises questions about the intended behavior of the comfort access system when the key fob is detected inside the vehicle and whether it’s linked to the intermittent unlocking problems.
While the exact cause remains unclear without professional diagnosis, several factors could contribute to these key fob and comfort access malfunctions in a 2015 BMW. These could range from a weakening key fob battery, which might be more susceptible to temperature changes, to issues with the car’s comfort access sensors located in the door handles or touchpads. Less likely, but still possible, could be interference from external radio frequencies or even a more complex issue within the car’s computer system controlling the comfort access.
For BMW owners experiencing similar problems with their 2015 key fobs and comfort access, especially the inability to reliably open their car, several steps are advisable. Firstly, ensure the key fob battery is fresh and of good quality. Secondly, observe if the issue is consistently related to temperature or other environmental factors. If the problem persists, scheduling a diagnostic appointment with a certified BMW dealership is crucial. They possess the specialized tools and expertise to accurately pinpoint the root cause, whether it’s a faulty sensor, a software glitch, or a more complex electrical problem within the comfort access system. Sharing experiences and insights within the BMW owner community can also be valuable in identifying common issues and potential solutions.
