Key Fob Programming & Replacement

Complete Key Fob Services

Modern vehicles rely on key fobs for convenient keyless entry, trunk access, panic alarms, and remote start features. When your key fob stops working or becomes unreliable, it's more than just an inconvenience—it impacts your daily routine and vehicle security. JustCarKeys specializes in diagnosing and resolving all types of key fob problems, from simple battery replacements to complete fob programming and replacement.

Our mobile technicians carry extensive inventories of replacement batteries, new key fobs, and professional programming equipment. We can diagnose whether your fob needs a battery replacement, re-programming, or complete replacement—and we handle the solution right at your location. Unlike dealerships that often require appointments days in advance and charge premium prices, we provide same-day service at affordable rates that typically save you 40-60% compared to dealer pricing.

We work with all vehicle brands and all types of key fobs, from basic remote entry systems to sophisticated proximity fobs with push-button start and remote start capabilities. Our technicians are trained on multiple systems and stay current with the latest key fob technology. Whether you drive a domestic vehicle, Japanese import, European luxury car, or Korean brand, we have the expertise and equipment to service your key fob professionally.

Key Fob Battery Replacement

The most common key fob problem is simply a dead or weak battery. Most key fob batteries last 3-4 years, but usage patterns and environmental factors can shorten battery life. When your fob's range decreases, buttons become unresponsive, or the fob works only intermittently, a battery replacement often solves the problem immediately.

JustCarKeys carries replacement batteries for virtually all key fob types. Our technicians can quickly identify your fob's battery type, open the fob casing carefully to avoid damage, replace the battery, and reassemble the unit properly. The entire process takes just a few minutes, and we test the fob thoroughly before completing the service to ensure all buttons and functions work correctly.

We also provide battery replacement for fobs that have been water-damaged or dropped. In these cases, we inspect the internal circuit board for damage and advise you whether repair or replacement is the better option. If only the battery needed replacement, we'll have you back up and running immediately. If the fob sustained internal damage, we can provide and program a replacement fob right away.

New Key Fob Programming

If you've lost your key fob, need an additional fob for a family member, or your existing fob is damaged beyond repair, JustCarKeys provides complete key fob replacement and programming services. We maintain an extensive inventory of OEM (original equipment manufacturer) and high-quality aftermarket key fobs for all major vehicle brands.

New fob programming requires specialized equipment that communicates with your vehicle's security system. Our professional-grade programming tools access your car's receiver module to register new fobs and delete lost or stolen ones. This process synchronizes the fob's RF (radio frequency) transmitter with your vehicle's receiver, ensuring all features work properly including door locks, trunk release, panic alarm, and remote start (if equipped).

We can program multiple fobs during a single service call if you need spares for family members or want backup fobs. Some vehicles limit the number of fobs that can be programmed, but we can often delete old fobs to make room for new ones. The programming process typically takes 15-30 minutes per fob, and we always test all functions thoroughly before completing the service.

Remote Start and Advanced Features

Many modern key fobs include remote start capabilities, allowing you to start your vehicle from a distance to warm it up in winter or cool it down in summer. If your remote start feature has stopped working or you're adding an aftermarket remote start system, JustCarKeys can program the fob and ensure proper integration with your vehicle.

Remote start programming is more complex than basic keyless entry because it must integrate with your vehicle's engine control systems, security features, and in some cases, automatic climate control. Our technicians understand these integration requirements and ensure your remote start works safely and reliably. We verify that all safety features function correctly—such as hood sensor, brake override, and automatic engine shutdown after the specified time period.

For vehicles with factory remote start, we can program replacement fobs to restore this feature. For vehicles without factory remote start, we can discuss aftermarket options and provide professional installation and programming. Our goal is to ensure your key fob delivers all the convenience features you expect while maintaining your vehicle's security and safety systems.

Proximity Key Fob Systems

The latest vehicles use proximity key fobs that allow completely keyless operation. These sophisticated systems detect when the fob is near the vehicle, automatically unlocking doors when you grab the handle and allowing engine start with a push-button—no key insertion required. Proximity fobs are convenient but also more expensive to replace through dealerships.

JustCarKeys provides proximity key fob replacement and programming at significantly lower cost than dealerships while maintaining the same quality and functionality. We work with all major proximity key fob systems, understanding the differences between various manufacturers' implementations. Our programming ensures your new proximity fob works correctly at the proper distances, responds to all door handles, activates the push-button start, and integrates with any remote start features.

Proximity fobs can also experience unique problems such as interference from other electronic devices or sensitivity changes due to battery drain. Our technicians can diagnose these issues and provide solutions, whether that's fob replacement, re-programming, or simple battery replacement. We ensure your proximity key fob delivers the convenient keyless experience you expect from this premium feature.

Troubleshooting Key Fob Problems

Not all key fob issues require replacement. JustCarKeys provides professional diagnostics to determine whether your fob problems stem from the fob itself, your vehicle's receiver, or an interference issue. Our systematic troubleshooting approach saves you money by identifying the most cost-effective solution.

Common Problems We Diagnose:

• Intermittent operation: Often caused by weak battery, water damage, or worn button contacts
• Reduced range: Usually indicates battery replacement needed or receiver antenna issues
• Specific buttons not working: May require fob replacement or sometimes button contact cleaning
• Fob not recognized: Could be programming issue, receiver problem, or internal fob failure
• All fobs not working: Typically indicates vehicle receiver or fuse issue rather than fob problem

Our diagnostic process includes testing your existing fob, checking for interference sources, verifying your vehicle's receiver operation, and testing with a known-good fob when necessary. This thorough approach ensures we identify the actual problem and provide the right solution the first time.
