Experiencing frustration with your key fob failing to start your car is a common modern-day inconvenience. Especially on a cold morning or a scorching afternoon, the remote start feature is a welcome convenience. But what happens when you press that button and… nothing? Before you assume the worst or rush to the mechanic, let’s explore the top reasons why your key fob won’t start your car, and how you can potentially troubleshoot the issue yourself or know when it’s time to call in the professionals at Auto Image. This guide will walk you through the most frequent culprits behind a non-responsive key fob remote start, helping you understand the problem and find a solution to get your engine running smoothly again.
1. Is Your Remote Start in Valet Mode?
Many advanced car remote start systems include a “valet mode,” a feature designed to prevent unauthorized use of the remote start function, typically when your car is being serviced or parked by a valet. When activated, valet mode usually disables the remote start capability while still allowing you to lock and unlock your doors using the key fob. It’s surprisingly easy to accidentally engage valet mode, sometimes just by pressing a sequence of buttons on your key fob while it’s in your pocket or bag.
The good news is that disengaging valet mode is usually straightforward. Often, your remote control or owner’s manual will provide instructions on how to exit valet mode, frequently involving pressing a combination of two buttons on your key fob. In some cases, a physical “kill switch” located under the dashboard might be responsible for activating valet mode. If you suspect this, simply locate the switch and toggle it back to the “on” position.
If you’re unsure whether your system is in valet mode or how to disable it, don’t hesitate to reach out to the experts. At Auto Image, our experienced technicians are readily available to assist you. We can quickly diagnose whether valet mode is the issue and guide you through the steps to deactivate it, ensuring your remote start is functioning as expected without unnecessary hassle.

2. Hood Pin Switch Problems: A Safety Mechanism Gone Wrong
Remote start systems are engineered with safety as a priority. A crucial safety feature in virtually all car and truck remote starters is a mechanism to prevent the vehicle from starting when the hood is open. This is typically achieved using a hood pin switch or a hood tilt switch. These switches are designed to detect whether the hood is securely closed, preventing accidental starts during maintenance or when someone might be working under the hood.
However, these hood pin switches can be susceptible to damage or failure over time. A common scenario is a mechanic inadvertently leaning on the hood pin switch during routine vehicle maintenance, which can lead to it breaking or malfunctioning. When a hood pin switch fails, the remote start system might incorrectly register the hood as being open, even when it’s properly closed, thus preventing remote starting.
A telltale sign of a broken hood pin switch is when you attempt to remote start your car, and the parking lights flash multiple times, but the engine doesn’t turn over. Interestingly, your key fob’s lock and unlock functions will likely continue to operate normally because they are separate from the remote start safety circuit.
The good news is that replacing a broken hood pin switch is usually a relatively simple repair. At Auto Image, our skilled technicians are well-versed in diagnosing and fixing hood pin switch issues. We can quickly identify if a faulty hood pin is preventing your remote start from working and perform the necessary replacement to restore your remote start functionality efficiently.

3. Remote Control Programming Issues (and Battery Checks)
Losing the programming in your key fob’s remote start is less common, especially if you’ve had a professional, high-quality remote start installation from a reputable installer like Auto Image. Modern car remote starts are designed to retain their programming through various memory systems integrated into their features. However, like any electronic device, these systems can occasionally experience memory glitches.
The most frequent cause of a key fob seemingly losing its programming is actually a dead or weak battery in the key fob itself. Before assuming a complex programming issue, always check and replace the battery in your key fob. It’s a simple step that often resolves the problem immediately.
If a battery replacement doesn’t solve the issue, and your remote start still isn’t responding, it’s possible that the remote control has genuinely lost its programming. This can sometimes happen due to electrical fluctuations or other unforeseen electronic events. In such cases, reprogramming the remote control is necessary.
While some DIY guides might suggest reprogramming steps, it’s generally best to seek professional assistance for remote start reprogramming. Auto Image technicians have the specialized tools and expertise to accurately reprogram your remote control to your vehicle’s system, ensuring seamless and reliable remote start operation. It’s worth noting that investing in high-quality remote start systems significantly reduces the likelihood of encountering programming issues in the first place.

4. Accidental Second-Car Mode Activation
Some sophisticated remote start systems are designed with the capability to control two separate vehicles from a single remote. This feature is particularly useful for households with multiple cars equipped with remote start. However, this dual-car functionality can sometimes lead to confusion if your remote accidentally gets switched into “second-car mode.”
If you press the start button on your key fob or smartphone app and nothing happens, it’s worth considering whether your remote might have inadvertently entered second-car mode. This can sometimes occur from accidentally pressing a combination of buttons on the key fob. When in second-car mode, the remote will be attempting to communicate with a different vehicle’s receiver, hence the lack of response from your car.
Consulting your remote start system’s owner’s manual is the quickest way to determine if your system has a second-car mode and how to reset it back to controlling your primary vehicle. The manual will typically outline the specific button presses or procedures to switch between car modes.
If you’re unable to locate your manual or are unsure about the reset procedure, Auto Image technicians are happy to assist. We can quickly diagnose whether your remote is in second-car mode and guide you through the steps to reset it, ensuring you regain control of your car’s remote start function without frustration.
