The United States appeals the denial of its motion to reconsider the district court’s suppression order. The government argues that the challenged dog sniff of Keith Ludwig’s car was not a search under the Fourth Amendment, and that no warrant was required to search the car after the dog alerted. We agree and reverse.
BACKGROUND
At about 11:15 p.m. on December 12, 1992, Joel Nickles, a Border Patrol agent at the permanent checkpoint near Truth or Consequences, New Mexico, walked a trained narcotics dog through the parking lot of the nearby Super 8 Motel to see if the dog would find any contraband. R. Vol. II at 5-6, 16. Less than a week earlier the motel manager had given the Border Patrol permission to walk dogs through the motel parking lot for this purpose. R. Vol. II at 4(M1.
As Nickles and the dog were walking through the lot, the dog pulled Nickles over to Keith Ludwig’s Chevrolet Impala and alerted to the trunk, indicating that illegal drugs were in the trunk. R. Vol. II at 7. Around half an hour later Border Patrol agents began surveillance of the car, which continued through the night until Ludwig first approached his ear the next morning at 10:00 a.m.
Agent Phillip Sanchez, who had been sur-veilling the car, approached Ludwig five minutes later and identified himself. Ludwig acknowledged that the car was his, but denied the agent’s requests to inspect the car and look in the trunk. Sanchez then directed Nickles to have the dog sniff the car again, and the dog again alerted to the trunk. *1526 When Ludwig refused to open the trank, Sanchez took the keys from the ignition, opened the trunk, and found several large bags containing marijuana. R. Yol. II at 32-33.
Ludwig was indicted for possession with intent to distribute less than fifty kilograms of marijuana in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(D). After pleading not guilty,' Ludwig moved to suppress all the evidence seized by the Border Patrol agents. The district court held an evidentiary hearing but did not hear Ludwig’s evidence, granting the motion after the government’s evidence on the grounds that the agents should have sought a search warrant because there were no exigent circumstances. R. Vol. II at 44-45. The court subsequently denied the government’s motion to reconsider, from which the government appeals.
DISCUSSION
I. Search of Parking Lot
Nickles’ entry into the motel parking lot with the dog was a search under the Fourth Amendment if it intruded on a legitimate expectation of privacy.
See Rakas v. Illinois,
Ludwig suggests that he had a separate privacy interest in some portion of the parking lot that he rented along with his room for the night. Even if Ludwig did rent a parking space with his room, he would have no more expectation of privacy in a particular parking space than he or the motel owner had in the lot generally. His parking space was open to the street just as the rest of the lot was, as well as open and visible from the rest of the parking lot where the agents entered lawfully with the motel manager’s consent.
See United States v. Burns,
II. Dog Sniff
Ludwig also suggests that the dog sniffs of his car were unreasonable searches
*1527
because the agents had no reason to suspect that there were drugs in his car. Although the Border Patrol generally knew that the motel was a staging area for smugglers, Nickles initially did not have any reasonable suspicion that Ludwig’s ear contained drugs. He entered the lot with the narcotics dog routinely to sniff all the cars in the lot, without any particular suspicion. This case thus presents the previously unanswered question whether random dog sniffing of vehicles and other objects without prior lawful detention or reasonable suspicion violates the Fourth Amendment.
See United States v. Morales-Zamora,
The Fourth Amendment protects a subjective expectation of privacy only if society recognizes that expectation as reasonable or justifiable.
Oliver v. United States,
III. Search of Trunk After Dog Alert
A. Probable Cause to Search
Ludwig suggests that dog sniffs are not as reliable as courts often assume, and therefore the dog alert did not give the agents probable cause to open and search Ludwig’s trunk. He also suggests that the district court’s denial of the reconsideration motion implied a factual finding that the dog alerts were unreliable and thus did not give probable cause. We do not think the district court implied such a finding, but clearly based its order on the belief that a warrant was required. We therefore review this contention de novo, and conclude that the dog alert did give the agents probable cause to search Ludwig’s trunk.
Probable cause means that “there is a fair probability that contraband or evidence of a crime will be found in a particular place.”
Illinois v. Gates,
Ludwig also questions whether there ever was a dog alert giving probable cause for the search of his trunk. He argues that the first dog alert could not give probable cause because surveillance was not constant and because of the passage of time before the search. The second alert, he contends, was not sufficiently reliable because Nickles and Sanchez gave different accounts of the alert. As to the first alert, we do not think the half hour between the alert and the beginning of surveillance resulted in less than a fair probability that there were drugs in the car as indicated by the dog alert. The passage of time alone is irrelevant, since the drugs would remain in the ear unless someone removed them. As to the second alert, Sanchez testified that he did not know how dogs alerted, was not watching the dog that closely, and may not have remembered exactly what the dog did while sniffing and alerting. Nickles, the dog’s handler, testified that he knows how his dog alerts and that his dog did so after the second sniff. The factual discrepancies between their accounts do not support the conclusion that the alert never happened or was itself unreliable.
B. Search of Trunk Without Warrant
Finally, Ludwig argues and the district court held that the search was unreasonable because the agents did not first obtain a warrant. We review this conclusion of law de novo.
United States v. Lugo,
A warrantless search of an automobile is reasonable if there is probable cause to believe it contains contraband.
United States v. Ross,
*1529
Ludwig also suggests that the auto exception does not apply here because his car was neither on the highway nor was it “readily capable of such use and ... found stationary in a place not regularly used for residential purposes — temporary or otherwise.”
California v. Carney,
IV. Remand for Ludwig’s Evidence
The district court did not hear Ludwig’s evidence at the suppression hearing. Ludwig asks that if we reverse we remand so that he may present his evidence. Appellee’s Br. at 22. We agree that Ludwig should be given an opportunity to present his evidence.
See Fulton v. L & N Consultants, Inc.,
We therefore reverse the district court’s denial of the motion to reconsider its suppression order and remand for further proceedings consistent with this opinion.
Notes
. Of course, the government agent may not unlawfully enter an area in order to conduct such a dog sniff. The physical entry itself may intrude on a legitimate expectation of privacy. This requires separate analysis, however, and we have explained above that the agents’ entry into the parking lot and Ludwig's parking space did not intrude on a legitimate expectation of privacy and therefore was not a search under the Fourth Amendment.
