2002 Saturn L200 Key Fob: Technical Specifications and Replacement Analysis
Key Takeaways
- Compatibility: The 2002 Saturn L200 utilizes a Remote Keyless Entry (RKE) transmitter operating at 315 MHz.
- Battery Type: Requires a standard CR2032 3V lithium coin battery.
- Programming: Owner-programmable via ignition cycle sequence; no diagnostic scan tool required for standard remotes.
- FCC ID: Verify the FCC ID on the back of your existing remote (commonly OUC60270T or similar GM Delphi series) before purchasing replacements.
- Ignition Key: Note that the RKE fob is separate from the mechanical ignition key, which typically does not contain a transponder chip in this model year.
Technical Specifications and Hardware Analysis
The 2002 Saturn L200, part of the GM L-Series platform, employs a radio frequency identification system for door lock actuation and trunk release. Understanding the hardware constraints is critical for sourcing compatible replacements. Unlike later GM models utilizing integrated transponder keys, the L200 separates the mechanical ignition function from the remote entry system.
Frequency and Signal Identification
The remote operates on the 315 MHz frequency band, standard for General Motors vehicles of this era. When sourcing a replacement, matching the FCC Identification number is more reliable than matching the vehicle model alone, as GM utilized multiple suppliers during the 2000-2005 production window.
Power Source
Signal degradation is most commonly caused by battery depletion. The unit is powered by a CR2032 battery. Replacement involves separating the housing halves via the key ring slot or a small flathead instrument, ensuring the circuit board contacts are not damaged during separation.
Replacement Option Comparison
Consumers generally face three distinct pathways for replacement: Original Equipment Manufacturer (OEM), Aftermarket Universals, or Professional Locksmith services. The following table analyzes the cost-benefit ratio of each approach.
| Replacement Method | Estimated Cost | Programming Difficulty | Compatibility Guarantee | Warranty |
|---|---|---|---|---|
| OEM (Dealer) | $80 - $150 | Low (Pre-programmed or simple sequence) |
