00:00So your BMW key finally gave up, the buttons stopped working, the case cracked, or you just lost the spare
00:05somewhere between the couch cushions and the abyss.
00:08And then the dealership quotes you 300 bucks in change for a replacement.
00:13Yeah, no thanks.
00:15I went digging and found 5 replacement key fobs that BMW owners are actually buying by the thousands, some of
00:21them for under $10.
00:23Let's get into it.
00:25First up is the key you remote key built for CAS3 systems, that's your 1, 3, 5, and 7 series,
00:31plus X5, X6, E60, E70, E90, and Z4.
00:36What I like here is that it covers 315, 433, and 868 MHz, so whatever region your car came from,
00:44there's a version that matches.
00:46It's got the PCF7953 chip inside, which is the real deal, not a dummy shell.
00:53$9.19
00:55Nearly 5,000 sold with a 4.9 rating.
00:59If you've got an older e-chassis BMW, this is honestly the easiest starting point.
01:04Now if you want to go even cheaper, the Jinjiokun CAS3 and CAS3 Plus key comes in at $7.43.
01:12That is less than a sandwich.
01:16Same PCF7953 transmitter chip, same wide model coverage across E60, E70, E90, and the X5 and X6, and it even
01:23includes the 315 LP frequency option, which a lot of the cheap knockoffs skip entirely.
01:28Over 4,200 sold, 4.9 stars.
01:33Just take it to a locksmith or use a decent programmer and you're back in business for pocket change.
01:39Stepping up to the newer cars, this is the key-use smart key for F-series BMWs running FAM or
01:44CAS4.
01:45So think 2014, 2015, and up, 5-series, 7-series, X5, X6.
01:52This one's proper keyless entry with the ID49 chip and the PCF7945P, 3 or 4-button options, and full 315,
02:00434, 868 coverage.
02:04It's $23.67, which is the priciest on this list, but compare that to what BMW charges for an F10
02:10smart key and you'll feel pretty good about it.
02:13Over 4,000 sold, 4.9 rating.
02:17Very similar territory, slightly different flavor, the key U3 and 4-button fob for the 5 and 7-series F
02:23chassis, covering FEM, BDC, CAS4 and CAS4 Plus from 2012 through 2017.
02:29The thing worth noting here is it's built around the IGOHA 5662 and 5767 part numbers, so if you check
02:36your old key and see those codes, this is a direct match.
02:401998, so about 4 bucks cheaper than the last one, with 4.8 stars and nearly 4,000 sold.
02:47Great pick if your original fob is just worn out.
02:50And last, the Leo smart key for CAS3 cars, and this one's sitting at a perfect 5-star rating, which
02:56you almost never see.
02:58It fits the same E60, E61, E70, E71, E87, E90 and Z4 lineup, runs the ID46 chip, and supports Keyless
03:07Go, so you get that comfort access feel on an older car.
03:11$10.47
03:13$3,500 sold
03:16For me, this is the sweet spot, barely more than the budget options, but the build quality feedback on it
03:21has been genuinely excellent.
03:23All 5 links are down in the description, so grab whichever one matches your chassis and frequency.
03:29If this saved you a trip to the dealership, do me a favor and hit that like button, and subscribe
03:34for more car stuff like this.
03:36Catch you in the next one.
