1. Initial Consultation and Assessment 

  • You can call or book our Baltimore mobile locksmith team. 
  • We ask for vehicle make, model, and year to identify fob compatibility. 
  • We estimate the cost and arrival time, ensuring clarity from the start. 

Booking info and pricing details can be found on our service page. 

2. Gathering the Right Key Fob Type 

  • We carry OEM-compatible or aftermarket key fobs matching your vehicle. 
  • Some brands need specific hardware modules (e.g., Honda, BMW). 
  • We check your wiring or programming chips to pick the correct unit. 

For uncommon vehicles, we may need to order a specific fob, typically delivered within a day. 

3. Deactivating Lost Fobs 

  • If your previous key fob was lost or stolen, we can erase it. 
  • Using vehicle diagnostics, we unpair old fobs to prevent unauthorized access. 
  • This enhances security and gives you peace of mind. 

Service steps like this are covered in our automotive locksmith service page. 

4. Programming Your New Key Fob 

  • We use professional-grade diagnostic tools and software. 
  • Our technicians connect directly to your car’s OBDII port. 
  • We program the new fob according to manufacturer’s guidelines, including rolling codes. 
  • Tests are run to confirm lock, unlock, trunk pop, and ignition functions. 

Some vehicles require two fobs for programming; we can bring a temporary one during service if needed. 

5. Physical Key Cutting and Blade Insertion 

  • If your fob includes a mechanical key blade, we cut it on-site. 
  • Precision cutting ensures correct groove alignment and smooth door unlocking. 
  • Tested immediately after to validate fit. 

For transponder or high-security blades, we use laser key-cutting tools rather than generic blades. 

6. Testing All Key Fob Functions 

  • We methodically test every button function: lock, unlock, panic. 
  • If equipped, we also test ignition start. 
  • Range tests confirm that the fob communicates effectively up to 20–30 feet. 

We log all testing steps on-site in a service report for accountability and warranty purposes. 

7. Final Calibration and Sync 

  • After programming and cutting, we resynchronize by locking/unlocking cycles as required. 
  • We clear fault codes from the vehicle’s immobilizer or remote modules. 
  • A final systems check ensures both the remote and ignition systems work seamlessly. 

This also includes resetting the vehicle memory to accept the new fob. 

8. Post-Service Support and Tips 

  • We provide a short warranty (typically 90 days) on parts and labor. 
  • Battery diagnosis and replacement recommendations are provided. 
  • Advice on storing spares and replacing batteries can prevent future lockouts.

FAQs 

1. Will the new fob require future software updates?
Generally, once programmed, key fobs do not require future updates unless your vehicle’s onboard computer receives a major update or reset. At Easter’s Lock & Security Solutions, we ensure compatibility with the latest firmware and guide you on when to consider updates, especially for newer or high-tech vehicle models. 

2. Can I duplicate a key fob without a working original?
Yes, even if you’ve lost the original fob, we can program a new one. Our technicians connect directly to your vehicle’s onboard system to sync a new fob. This is particularly helpful for lost or stolen fobs, ensuring your vehicle remains secure and fully operational without the original remote. 

3. How long is the warranty on our key fob services?
We provide a 90-day warranty on all key fob duplication and replacement services. This warranty covers defects in the fob, programming issues, and installation errors. If any problems arise within that period, Easter’s Lock & Security Solutions will replace or reprogram your fob at no extra cost. 

4. Do you provide spare key fob programming?
Yes, we highly recommend having a spare key fob for emergencies. During your service appointment, we can duplicate and program a second fob on the spot. Having an extra key fob not only offers peace of mind but also avoids future inconvenience and additional programming costs. 

5. Can you fix damaged key fob casings?
Absolutely. If your key fob shell is cracked, worn out, or broken, we can transfer its internal electronics into a new casing. This is a cost-effective and environmentally friendly solution. It restores functionality and durability without the need to replace the entire electronic unit or reprogram it.
 

6. What types of vehicles can you service for key fob replacement?
Easter’s Lock & Security Solutions services a wide range of vehicles—from domestic to foreign brands, including cars, trucks, and SUVs. Whether you drive a Ford, Toyota, BMW, or Tesla, our team has the tools and technology to duplicate or replace key fobs for most modern vehicle models.
