What gets confused with this FCC ID
Several common mismatches show up on aftermarket marketplace listings. The FCC ID labels printed on the back of fobs are sometimes wrong because the listing was created from a similar-looking fob. The chip inside two fobs with the same FCC ID label may be a genuine NXP or Texas Instruments chip in one case and a clone chip in the other. The button layout looks identical but the button mapping in the radio profile is slightly different.
The way to avoid these issues is to confirm the FCC ID on the back of your existing fob (in small printed text near the battery compartment), confirm the button count and arrangement matches, and confirm the chip family before ordering. We do this verification as part of the call before dispatch.
What we bring for this FCC ID
Our mobile unit carries OEM-equivalent replacements for the common FCC IDs, including KR5TP-4 where vehicle compatibility matches. We also carry CR2032 batteries (the most common coin cell for this fob family) so a simple battery replacement does not require a separate trip.
Common scenarios we see with this FCC ID
- Battery replacement that does not restore function. The owner changes the coin cell but the fob still does not respond. The cause is usually a cracked internal antenna trace from a drop, not the battery. Fob replacement is the typical fix.
- Aftermarket fob installed and failed weeks later. A marketplace fob with the right FCC ID label but a clone chip passes initial programming, then fails when the immobilizer rolling code advances. We replace with an OEM-equivalent and reprogram.
- Spare fob requested by a household with one working original. The household has two drivers and one fob; a planned spare avoids the eventual emergency. We program the spare while the original still works, which keeps the job simpler.
- Lost-all-keys scenario after a used vehicle purchase. The previous owner did not deliver all the keys. We use the VIN to cut and program a new fob from scratch, then optionally delete any keys still in the immobilizer's memory so prior fobs no longer work.
Programming considerations specific to this FCC ID
Honda HDS or AUTEL IM608 required. Newest Honda IMMO system. Programming time on-site is shorter for a working-key spare and longer for a lost-all-keys job. We test the new fob's door lock, unlock, trunk function if applicable, and engine start before collecting payment.
Frequently asked about FCC ID KR5TP-4
How do I confirm the FCC ID on my fob?
Look at the back of your existing fob. The FCC ID is printed in small text, usually near the battery compartment or on a sticker inside the battery cover. The text starts with letters followed by digits, for example KR5TP-4. The label is not always immediately obvious; check carefully.
Is FCC ID KR5TP-4 the same across all model years it appears on?
Generally yes within the year ranges noted above, but the firmware inside the fob is sometimes updated mid-cycle. Confirm by year, make, and trim, not just by FCC ID, especially for newer model years.
Can I order a replacement fob online and bring it to you for programming?
Yes, with caveats. The fob must match the FCC ID exactly and use a genuine chip from a major supplier. If you bring an unknown-brand fob with a clone chip, programming may succeed but the fob often fails within 30 to 60 days. We prefer to source the fob ourselves to ensure quality, but we can program a customer-supplied fob if you have already purchased one.
Inside the FCC KR5TP-4 radio profile
The radio module identified by FCC ID KR5TP-4 carries an authenticated radio profile that the U.S. Federal Communications Commission has certified for use on passenger vehicles. The profile defines the transmit frequency (typically 315 MHz in North America), the modulation type (usually ASK or FSK), the power output level, and the duty cycle. Two fobs that share an FCC ID share that radio profile and are therefore interchangeable from a regulatory standpoint, though the immobilizer authentication keys remain vehicle-specific.
The chip inside the fob is independent from the FCC-certified radio module. The chip handles cryptographic authentication with the vehicle's immobilizer module; the radio handles the door lock and unlock signals. Both must work for the fob to be fully functional. A failure in either subsystem looks like a fob problem from the driver's perspective but is diagnosed differently by a technician.
What a programming session actually looks like for FCC KR5TP-4
An on-site programming session for a fob in this FCC ID family starts with the technician confirming the vehicle's immobilizer is communicating with the OBD-II programmer. The programmer reads the current immobilizer state, including any fobs already enrolled. The technician then puts the immobilizer into key-add mode, enrolls the new fob, and the programmer writes the new fob's authentication key into the immobilizer's secure memory. The session ends with a verification cycle: door lock, door unlock, ignition cycle, and engine start to confirm the new fob authenticates properly.
The whole sequence is shorter for a working-key spare job and longer for a lost-all-keys job. The difference is the PIN retrieval step that lost-all-keys requires.
Fobs sometimes confused with FCC KR5TP-4
Fob FCC IDs in adjacent families can look similar enough to cause ordering mistakes. The most common pattern is a marketplace seller listing a fob as compatible with multiple vehicles when only the radio profile matches; the chip family or button count differs in a way that prevents successful programming. The way to avoid this is to confirm the FCC ID on the back of your existing fob letter by letter and digit by digit before ordering anything online.
OEM and OEM-equivalent fobs from major aftermarket suppliers (Strattec, Hella, Keyline) are reliable. Unknown-brand marketplace fobs frequently use clone chips that pass initial programming, then fail authentication 30 to 60 days later as the immobilizer rolling code drifts beyond the clone's authentication window. We see this pattern consistently across all common FCC IDs, not just KR5TP-4.
